Thanks for watching! We really didn’t have long to produce this video and the render took over 6 hours!! We noticed 3 graphical glitches at 1:54 - 2:03 and 2:24 - 2:27.

@@theautomationchannel6920 just take out some contrast? The would defeat the purpose of an accurate test. He set up a shot. Both cameras equal they should have equal tones. A7IV is darker every time, you probably prefer A7IV style buts not accurate to how he has the scene set up.
I was looking through the comments wondering if I was the only one lol. I actually preferred the contrast and colors of the a7iv (specifically the reds and greens)
It would be interesting for you to dig into the crop mode more. That should help the rolling shutter if it was an issue. Seeing the tradeoff in noise and sharpness would be of interest. A lot of us have crop lenses and this might make a nice step up if the crop performance is decent.
At 4:54 you said you changed the lighting to compensate... I'm not clear if that's why there's a difference in contrast, or the way the sensors are rendering. The luminance still looks different. You could have used the ISO setting to change and report the difference. Anyway, thanks for providing this comparison. I do like the colors better on the IV (personal pref of course), but seeing them at the same brightness (even matching with the histogram) would have been helpful.
I hate to say it - but it seems to me that Sony engineered this camera to purposefully under perform in certain areas so as not to canibalize their A7S3 and other models.
Actually no. It’s mainly the choice of 33mp sensor that hampers the video capabilities. It’s why it has to crop to achieve 50/60fps in 4K. One of the reasons the A7SIII has 12MP is not only the light sensitivity, but also the readout speed for better rolling shutter and more easy high framerate processing. Hence it can do 4K 50/60fps easy. And 4K 100/120fps with only a slight 10% crop. I wish Sony had kept 24MP for the A7IV but maybe a new sensor and using this Xmor R processor (Same as A1 and A7IV) but just keep the resolution normal so the 4K 50/60fps would be possible without a crop. But clearly they had to cater to mostly the photography consumers here and make the camera lean a bit more to the photo side of the market. As any serious videographer would already be inclined to get the A7SIII anyway.
@@bananasandbass I’d have to disagree. Since the A1 has a higher MP count and and the A74 shares the same processor and the A1 sensor and was developed Before the A74 - they had the technology to give the lower MP A74 sensor the same faster readout. Companies do these kinds of “dummying up” their products all the time so as not to canabalize their other products.
@@tennissir1986 One important detail explains the difference. The A1 has a stacked sensor. A kind of RAM is integrated on that chip (similar to A9). Which is the fundamental first step in a fast image process pipeline. The A7IV doesn’t have that, it “only” has the image processor. I would have liked them to keep the 24MP but make it a faster sensor and add that Xmor R processing after that. But that would also make it a more expensive camera. Which is not what this base model FF mirrorless is about.
I was going for the A7SIII after my current A7III as video is becoming more important. I was surprised and glad to see the color accuracy and dynamic range of the SIII holds up way better.
This is a very well detailed comparison. Thanks for sharing this! I have been wondering the comparisons between the A7sIII and the A7 IV, and this video answered a lot of questions for me. One thing I was definitely taken a back by was the color between the A7sIII and A7 IV. You didn't mention what color profile and LUT you used during the ISO and Noise comparisons, but the colors seemed quite different. Were they both using Slog3 and a Rec 709 LUT?
Quick question. Why are some of you guys insisting on using canon's "mark" designation for model name? I've not heard any Sony rep or seen it in or on site or documentation. Just asking!
Happy to see this review, very different from others that are not from a pro video/film perspective. The differences in tonality with the A7S3 / FX3 you show are an eye opener. Combined with the rolling shutter and the lack of real slow-motion, the FX3 is still the bare minimum to make serious film content. I really hope the new features like "focus breathing compensation" and skin tone choices make it to the FX3 / A7S3 with a firmware.
Thanks for the great overview. You guys do a wonderful job. The detail difference between the R6 and the A7IV was quite stark when you had both on the screen with the color charts up. Almost to the point that the Sony would need to have some detail dialed back for shooting people. With the stronger codec options, color differences seem to be less important these days as they can be altered in post. This camera looks like a great tool in the end that will not lead any spec categories but be very useful.
CVP is the best! Love you guys! Biggest disappointments are the S35 4K 60p and the differences in color to the A7SIII. This is a beast of a stills camera though.
The letdown by α7 IV's _uncompressed_ raw burst [1], confirmed 6 fps [2], is overblown [3].

That's all done, if at poorer autofocus, by α7 III [5]. Yet an α7 IV for raw 10 fps-useful on noncritical action [2], like a subject staying on axis or predictable [4]-might cost 2900 USD.

Sony's quiet shutters, new in 2015's 42MP α7R II, quelling camera shake, aid resolution, but 24MP α7 III's loud clunks, like DSLR mirror shock, seemingly return for α7 IV's 38% more pixels. The α7 IV's 33 MP are some 65% beyond its mirrorless rival, Canon R6-solid 12 fps raw [1]-and 2020's flagship DSLRs, Canon 1DX III and Nikon D6, all some 20 MP.

Hi, verry verry interesting !! Best video for sure. O'e question if you read me, i ve got a R6 just for skinstones (the a7 III was awfull). Do you think the a7 4 has improved enough and be able to challenge Canon (just for the skin tones of course)? Many thanks.
Great video. If you were a wedding photographer who doesn't crop photos, and you needed a camera, which camera would you choose? The Sony a74 or the a7siii? Please tell me why?
Yes, this is a review!! wow. Thanks. I think this might be the one that makes me upgrade. I don't mind the APSC 4k 60 as I mostly shoot S35 these days anyways. FF lens prices have gone off the roof.
Wow..thanks for the overview. Spectacular job. Are you testing autofocus/face detection in 4k/60p and 180/120p? . Still works autofocus in slow motion?
I know that the two base ISO of A7SIII while shooting S-Log 3 is 640 and 12800 And for S-Cinetone is 100 and 2000 But what is the duel Base ISO of A7SIII while not using any Picture Profiles?
Thanks for the review man! Would you please tell me whether the A7IV can shoot 1080p 100/120FPS in 10 bit 4:2:2?? or it is limited to 8 bit codec? I'm really confused I heard different things about it
erm.. the fan comparison is a bit weird?! 4k25/50 vs 4k120 and HD120?! isn't it logical, that the readout speed is alot higher in 4x higher fps modes? xD
Yeah should have included the 25p tests we shot (which the script is based on) instead of the 120p. It still doesn’t take away from how slow the a7 IV is though.
Hi. Thanks for your great reviews! I have a question: Is it possible to apply the s-cinetone profile on the hdmi out? Thank you and keep up the good work.
I’m a bit confused, seems like the footage shifts from green-ish to purple-ish during iso range. A fast vector-scope img. would help. (I understand that u cant provide it all).
How about test shots of the Sony a7iv 4k crop 60fps with Sony 16-55 f2.8 lens? The new Tamron aps-c Zoom lenses and the Sigma new aps-c Zoom lenses. Also, do several similar tests with Fuji aps-c prime lenses for Sony e-mount: Fuji 16mm f1.4; Sigma 19mm f/2.8; Sigma 30mm f/1.4; Sigma 56mm f/1.4.
Hi, out of curiosity: I only make documentaries in 4K 50p only freehand. I don't take pics. I never use a tripod or gimbal. Do you think I can handle this SONY ALPHA 7 IV well or is it better to think of another camera like the Panasonic? I will need an all-purpose zoom lens, what do you suggest please. Thank you.
Great video. Thank you. Can you tell me if you can shoot 24frames in the crop mode, and if so, does this help the rolling shutter? That plus a wider lens might make this viable. Thoughts?
I think you can. And doing so for sure will improve the readout as it would be a smaller portion. Not sure where I've read it goes down to 13 ms in crop mode 👍🏻
Why is Sony avoiding adding Shutter Angle to their cameras? It is a simple software tweak and most of their cameras are around $3K. The GH5 and all Panasonic cameras have this feature.
Hi CVP, thank you for doing the video of A7IV, very informative. I thinking of upgrading Sony A7IV from my A7III. However, there is not much information about the Full HDMI functionality of the camera. My current A7III, I use Mini HDMI connect to Elgato Cam Link 4k and feed to my software from there. With the A7IV, can I do the same setting from Full HDMI to Full HDMI to my 4K Elgato Capture card. I know A7IV can use USB C for streaming but the 4K only 15p, not really, it would be a lot of chopping in the video. If I use the full HDMI port to the Elgato 4K Capture, would be able to run 4K 24p/30p? , much appreciated if you can reply. Thank you
Great review, thank you so much! You guys always deliver quality. I actually preferred the look of the A7IV compared to the A7SIII during the shot of the man next to the color chart. The A7IV looks much more realistic to me, whereas the A7SIII looks sort of oddly low contrast and tinged with magenta. Of course it's only a few shots so I'm not drawing any conclusions. However, seeing as it's such a subjective thing to judge, might I suggest you phrase your conclusions about colors a bit more like "all our testers liked the look of the A7SIII more" rather than "the A7SIII has better colors"? Uh oh, looks like I'm nit picking on the internet again! Better log off. Cheers, lads!
What? Are you guys for real? can you rephrase it to "all our testers liked the look of A7SIII?" Lol. You got to be kidding me. No one has an issue with this except these weirdos, cause the video is literally showing you a color chart for color accuracy and if one holds it's colors better then it's clearly better colors. It's a fact not Subjective. You preferring a shifted color tone it's subjective. Uh oh I'm nit picking on the internet again. Bye guys cheers. Lol 😂.
accordibng to Cined, the a7 IV has better D.R....so , that does not match your results here. And, about ISO, you shuold metion that the Dual native ISA on a7 IV is different, its 800/ 3200, vs a7 sIII is 640/12800 . Also you dont mention that the a7 IV is sharper ?
Thank's for the review! Acording to you'r example it look's that the stabilazyzer is not god/ speccialy when you walked Compering to panasonic similar cam. Correct me if im wrong.
Digging the skin tones of the IV.. Less bloom and more neutral colors...reminds me of the colors of the first cinealtas which I preferred. The RS is a total disappointment though. A7siii is 7.8ms this is probably back in the 25ms range. I am looking to Sony to continue the reduction of RS..(Amira sub 3ms would be a goal) not go backwards.
im happy I got my Panasonic S5, contemplated holding off for the A7IV but in terms of video features and price im happy with my choice after watching this
Nice to bear! I just waited for this release to make my decision for the S5. For 800 euro’s less I can get the S5 with 20-60 en 50mm 1.8 lens. Is the lowress viewfinder workable for you?
@@CorLievendag The viewfinder is very usable, I think if youre more into shooting stills the Sony might be worth the money, but it's still a maybe, the price difference is a lot
@@umpopablebubble thank you! I shoot more video’s, so at first I was looking at the GH5ii. But I think the S5 is better deal. I read that the focus peaking was hard on the S5. I had the Panasonic FZ1000 before and I liked the colors more toen my Sony RX10IV.
@@CorLievendag The focus peaking is not that good, especially at lower apertures. IBIS is good, slightly shaky at like 16mm/20mm, but after that it does good. Editing in V-log and the regular profiles is easy, and the custom menu options are fantastic.
Hi, thanks to share your interesting video. I'd like to ask a question please: I make only documentaries in 4K around the world, I don't take Pics. I take interest about a good image quality of the video. Do you suggest this Sony A7 IV camera for 4K videos? Thanks you.
Hello, what’s your budget? Have you got E mount lenses already? If you strictly just shoot video there are better options in this price range. This camera is aimed more as a hybrid with a slight lean towards photo performance. Jake
@@CVPTV I thank you a lot for your suggestions. My budget is around the same of Sony A7 IV. but if it is a bit less it is better. I have to buy both, the camera and its lens but in kit (with zoom) because they cost less. What camera do you suggest for my 4K documentaries? I always reach remote areas of Africa and South Ameria to shoot the daily life of the indigenous peoples. I remind you I don't take pics and I inform you I only shoot handheld footage and I rarely use the tripod.
Thanks for the review! At least someone showed a comparison at super high ISO's. I wish you had explored and talked more about the crop mode in comparison to the FF mode. Do you remember if ISO 25600 is much worse on the crop mode? I would like to capture "nature stuff" and many times that would be at low light. At macro levels you'd want details while keeping a reasonable DoF (small apertures). Also I hope that Sony didn't get rid of the "Clear Image Zoom" in these modern cameras. I love that feature in my A7r II.
There's some confusion in the video, the author doesn't understand what "dual gain" is and thinks it's just "noise reduction", but actually it's something else entirely. Also the author doesn't understand why there is more detail and better noise in the A7iv, and again attributes the better noise to "noise reduction", but actually this simply because of the higher resolution sensor.
Sorry but this sensor isn’t officially dual native iso, you can see obvious signs of noise reduction on the port capped footage. If it was a proper dual native iso sensor, Sony would be stating it as they do with their cameras that do have it, ie fx9, VENICE, etc. I can assure you I am not confused by either of the subjects you have mentioned. Can you please explain your 2nd point as it’s pretty, confusing?
@@CVPTV He's referring to scaling down the image (7K down to 4K), which also scales down the noise. Many have discussed this as a benefit by potentially making the images look cleaner and sharper... and that is somewhat evident in your controlled test (sharper in this case), though not withstanding the color shift. Not my words, but those of Northrup, Cine-D, among others.
According to Gerald Undone and his tests on the Xyla 21 the dynamic range is actually a 3rd stop better than the a7siii due to the better noise performance as a result of the high mp downsampling, similar to the a1. The colours in your outdoor tests to me looked better on the a7iV as well.
Interesting… your review shows diff results… Jason Vong showed it’s actually Noisier video than a7iii. Gordon Laing showed it has same video resolution/IQ as a7iii.
Not sure what to tell you. Our methodology behind the tests was as follows. Both cameras set to SLOG3 SGAMUT3.CINE. Both cameras set to 4K 25, a7 III XAVC-S a7IV XAVC S-I at max data rates. Both cameras custom white balanced using a grey card. We then lit ISO 800 on the a7 IV with the aperture around T2. Using 41% +/- 1 Zebras, making sure our mid grey chip on the Macbeth chart was showing the Zebra. As we went up in ISO we stopped down the lens. We then did the same for the a7III adjusting T stop slightly to compensate the difference in exposure we were seeing at the exact same settings as a7 IV on the a7 III. Jason doesn't explain any of the methodology behind his test and even says it isn't perfect. I don't believe we mention the resolving difference between the a7 III and the 4 in this video do we, so how does it conflict with what Gordon is saying? Jake
@@CVPTV It would be cool if you reached out to them and figure out who is right! Us mega nerds looking for these particular stats would love it. Subscribed for the quality of this one video alone. Cheers!
Hello. I am watching your reviews and thank you for your work. I would like to advise you on buying 6k video recording equipment. £ 3,000 maximum The camera is to be used to record music videos and reportages. Thank you.
When everyone says that A7IV and A7Siii colour science is basically the same you prove the opposite. Maybe something was off with your A7IV files? Looks awful.
I didn’t understand the part with the charts and the latitude test. Why did the two cameras expose so differently on the same scene even with adjusted lighting? It’s even on the same log gamma curve no? Also did Sony cripple the a7iv somehow with worse color science as well? They definitely did not do its rolling shutter justice though, that is some 2013 consumer DSLR video jello effect I see.
Not sure if you understand what the word cripple means. It's pretty evident you don't. a7 IV footage can be easily intercut with footage from the a7s III. 30ms rolling shutter on the Panny S1H circa 2019 and not downsampled from 7K either, so not 2013. 20ms on the s35 sensor of the Pocket 6K, which is nothing to write home about either. 30ms on the Canon R5, circa 2020. You're not funny, maybe choose another career.
@@JonPais how much these cameras cost again? Maybe it has something to do with the cooling system and the processor used? Maybe that's why the R5 overheats?
Great review and feature breakdown / comparison, thanks! Where can I get the hot shoe mounted handle seen here ruclips.net/video/ORIdHKWzG0s/видео.html ?
On the one hand, I agree, but I think I understand what is going on. Contrast is always adjustable for every Picture Profile, and all the other preset system that Sony provides (I don't know why the include so many overlapping preset systems), so you should be able to match them for most situations if you want to do so. Sony seems to treat the default contrast as relative to the particular sensor in each of their cameras. Slog2 from my a6400 is not going to look like Slot2 from this a7iv, nor like the older a7iii. But if I want to, I can equalize them all to output about the same within limits. Compare that to Panasonic who created VLog-L for the GH5 which has the same slope as VLog, except that it clips early in the highlights instead. Is that better? I don't know. I understand the difference, but at this point, I can't say I have a preference.
Thanks for watching! We really didn’t have long to produce this video and the render took over 6 hours!! We noticed 3 graphical glitches at 1:54 - 2:03 and 2:24 - 2:27.

@@kaimelis You have to think about bit-rate, resolution, and how long the video is.
6 hours sounds about right, even for a super high end computer
5:10 "The A7s3 looks much better tonally"??? To be honest, for me, is exactly the opposite...
I was trying to understand why it is much better…
Just take out some contrast and they will match.
Same here - a74 had more detail and probably one needs t fine tune color etc differently for each camera & lens combination

O'e question if you read me, i ve got a R6 just for skinstones (the a7 III was awfull). Do you think the a7 4 has improved enough and be able to challenge Canon (just for the skin tones of course)?
Many thanks.
14:47 Oh my God! I've been wanting a tool like this for years! Maybe have a colored arrow on each square indicating which way to turn the lens?
Beautiful video. Did you shoot in slog3? Did you overexpose +2? What filters did you use exactly? What lens did you use?
Hello, i love the review. As usual excelent work ! Is it possible to shoot 4k 25p apsc mode on a sony a7iv ? Thanks
Fantastic review....honnest and to the point! Congrats!
Great video. If you were a wedding photographer who doesn't crop photos, and you needed a camera, which camera would you choose? The Sony a74 or the a7siii? Please tell me why?
Super interesting! Seems like there is quite a lot of IBIS wobble/jank.
Some shots have had some post stabilisation so this could be a result of that too. Jake
@@CVPTV cheers for the hard work guys.
It looks like the contrast between the two cameras are completely different. And in this case the comparison does not make much sense.
Damn it, THIS is a review!!! I need to see more times due to my english limit, but definetely I will :)
I have a four year plan to buy a selection of camera's past and present. The oldest being from 2015.
Yes, this is a review!! wow. Thanks. I think this might be the one that makes me upgrade. I don't mind the APSC 4k 60 as I mostly shoot S35 these days anyways. FF lens prices have gone off the roof.
What filters were used on the lens when filming? Looks interesting. Also great great video!
Thanks for an awsome review!
Wow..thanks for the overview. Spectacular job. Are you testing autofocus/face detection in 4k/60p and 180/120p? . Still works autofocus in slow motion?
Thanks for watching, yes the full autofocus system works in S&Q mode so should perform the same as when in the normal video mode. Jake
I know that the two base ISO of A7SIII while shooting S-Log 3 is 640 and 12800
And for S-Cinetone is 100 and 2000
But what is the duel Base ISO of A7SIII while not using any Picture Profiles?
Thanks for the review man! Would you please tell me whether the A7IV can shoot 1080p 100/120FPS in 10 bit 4:2:2?? or it is limited to 8 bit codec? I'm really confused I heard different things about it
It’s available in XAVC S-I which is 4:2:2 10bit. Jake l
@@CVPTV That's really awesome! And how much is the bitrate? Thanks again dude
erm.. the fan comparison is a bit weird?! 4k25/50 vs 4k120 and HD120?! isn't it logical, that the readout speed is alot higher in 4x higher fps modes? xD
Yeah should have included the 25p tests we shot (which the script is based on) instead of the 120p. It still doesn’t take away from how slow the a7 IV is though.
This is the a, fx3 is the b cam, given this has higher resolution.
Hi. Thanks for your great reviews! I have a question: Is it possible to apply the s-cinetone profile on the hdmi out? Thank you and keep up the good work.
I’m a bit confused, seems like the footage shifts from green-ish to purple-ish during iso range. A fast vector-scope img. would help.
(I understand that u cant provide it all).
How about test shots of the Sony a7iv 4k crop 60fps with Sony 16-55 f2.8 lens? The new Tamron aps-c Zoom lenses and the Sigma new aps-c Zoom lenses. Also, do several similar tests with Fuji aps-c prime lenses for Sony e-mount: Fuji 16mm f1.4; Sigma 19mm f/2.8; Sigma 30mm f/1.4; Sigma 56mm f/1.4.
Hi, out of curiosity: I only make documentaries in 4K 50p only freehand. I don't take pics. I never use a tripod or gimbal. Do you think I can handle this SONY ALPHA 7 IV well or is it better to think of another camera like the Panasonic? I will need an all-purpose zoom lens, what do you suggest please. Thank you.
The slomo of the A7S III can be done using the Chronos model on Topaz VideoEnhance AI.
Great video. Thank you. Can you tell me if you can shoot 24frames in the crop mode, and if so, does this help the rolling shutter? That plus a wider lens might make this viable. Thoughts?
I think you can. And doing so for sure will improve the readout as it would be a smaller portion. Not sure where I've read it goes down to 13 ms in crop mode 👍🏻
Should we expect new cages for A7iv or A7siii cage would fit there.???
I am tilta fan.. so is my cage A7siii would fit A7iv
Hello can you add compare aliasing for 1080 HD 50P resolution?
Why is Sony avoiding adding Shutter Angle to their cameras? It is a simple software tweak and most of their cameras are around $3K. The GH5 and all Panasonic cameras have this feature.
Hi CVP, thank you for doing the video of A7IV, very informative. I thinking of upgrading Sony A7IV from my A7III. However, there is not much information about the Full HDMI functionality of the camera. My current A7III, I use Mini HDMI connect to Elgato Cam Link 4k and feed to my software from there. With the A7IV, can I do the same setting from Full HDMI to Full HDMI to my 4K Elgato Capture card. I know A7IV can use USB C for streaming but the 4K only 15p, not really, it would be a lot of chopping in the video. If I use the full HDMI port to the Elgato 4K Capture, would be able to run 4K 24p/30p? , much appreciated if you can reply. Thank you
4k60p crop, low fps, rolling shutter, 1.03M screen...Too many compromises at this price point in 2021 given the success of R6, let alone A7iii's.
What filters and lenses did you guys use for this shoot?
Great review, thank you so much! You guys always deliver quality. I actually preferred the look of the A7IV compared to the A7SIII during the shot of the man next to the color chart. The A7IV looks much more realistic to me, whereas the A7SIII looks sort of oddly low contrast and tinged with magenta. Of course it's only a few shots so I'm not drawing any conclusions. However, seeing as it's such a subjective thing to judge, might I suggest you phrase your conclusions about colors a bit more like "all our testers liked the look of the A7SIII more" rather than "the A7SIII has better colors"? Uh oh, looks like I'm nit picking on the internet again! Better log off. Cheers, lads!
Fully agree that the A7IV looked better. I also think it should have worded their feedback (their preference to 7Siii colors) differently.
What? Are you guys for real? can you rephrase it to "all our testers liked the look of A7SIII?" Lol. You got to be kidding me. No one has an issue with this except these weirdos, cause the video is literally showing you a color chart for color accuracy and if one holds it's colors better then it's clearly better colors. It's a fact not Subjective. You preferring a shifted color tone it's subjective. Uh oh I'm nit picking on the internet again. Bye guys cheers. Lol 😂.
What’s that difference in specs /and feature between A7 IV and A7 S III ?
accordibng to Cined, the a7 IV has better D.R....so , that does not match your results here. And, about ISO, you shuold metion that the Dual native ISA on a7 IV is different, its 800/ 3200, vs a7 sIII is 640/12800 . Also you dont mention that the a7 IV is sharper ?
you also say that the M.R proboably is"more" in the a7 IV, this does not match the findings of Cined, who calims the oposite
Thank's for the review!
Acording to you'r example it look's that the stabilazyzer is not god/ speccialy when you walked
Compering to panasonic similar cam. Correct me if im wrong.
Waiting for the red raptor video !
@8:09 why are you comparing the a74's 25 fp with others cameras' 120 fp? Of course you will get a still fan when pausing at high frame rates.
how come the a7sIII lost all details on the face.....
Nice! #TeamSony
you guys make the best reviews, thank you for actually doing real world tests rather than using xyla charts
How does full hd footage looks in this camera?
Canon R6 for vídeo Not good ?
Is the 120fps in 10bit or 8bit? Thanks
You can record 120 in XAVC S-I HD which is 4:2:2 10-bit. Jake
Price and rolling shutter has paused my system upgrade from my old APC. I am dissapointed.
Digging the skin tones of the IV.. Less bloom and more neutral colors...reminds me of the colors of the first cinealtas which I preferred. The RS is a total disappointment though. A7siii is 7.8ms this is probably back in the 25ms range. I am looking to Sony to continue the reduction of RS..(Amira sub 3ms would be a goal) not go backwards.
im happy I got my Panasonic S5, contemplated holding off for the A7IV but in terms of video features and price im happy with my choice after watching this
Nice to bear! I just waited for this release to make my decision for the S5. For 800 euro’s less I can get the S5 with 20-60 en 50mm 1.8 lens. Is the lowress viewfinder workable for you?
@@CorLievendag The viewfinder is very usable, I think if youre more into shooting stills the Sony might be worth the money, but it's still a maybe, the price difference is a lot
@@umpopablebubble thank you! I shoot more video’s, so at first I was looking at the GH5ii. But I think the S5 is better deal. I read that the focus peaking was hard on the S5. I had the Panasonic FZ1000 before and I liked the colors more toen my Sony RX10IV.
@@CorLievendag The focus peaking is not that good, especially at lower apertures. IBIS is good, slightly shaky at like 16mm/20mm, but after that it does good. Editing in V-log and the regular profiles is easy, and the custom menu options are fantastic.
@@umpopablebubble IBIS/ergonomics/menu are always good with Panasonic! What lenses do you use?
Bro...Which budget Prime lens is most suitable for Sony A7IV???
Zoom or Prime? What focal length / range? Jake
@@CVPTV Prime for Portraits... 50mm f1.8 most probably...
Hi, thanks to share your interesting video. I'd like to ask a question please: I make only documentaries in 4K around the world, I don't take Pics. I take interest about a good image quality of the video. Do you suggest this Sony A7 IV camera for 4K videos? Thanks you.
Hello, what’s your budget? Have you got
E mount lenses already? If you strictly just shoot video there are better options in this price range. This camera is aimed more as a hybrid with a slight lean towards photo performance. Jake
@@CVPTV I thank you a lot for your suggestions. My budget is around the same of Sony A7 IV. but if it is a bit less it is better. I have to buy both, the camera and its lens but in kit (with zoom) because they cost less. What camera do you suggest for my 4K documentaries? I always reach remote areas of Africa and South Ameria to shoot the daily life of the indigenous peoples. I remind you I don't take pics and I inform you I only shoot handheld footage and I rarely use the tripod.
@@ExploringWorldRUclips spend/save extra and get the a7siii for the dual native ISO
@@dna8269 But I will have to carry with me even a tripod or a gimbal, it is the problem. Anyway I thank tou.
The purple shift when under exposed is really weird and quite bad tbh...
Thanks for the review! At least someone showed a comparison at super high ISO's.
I wish you had explored and talked more about the crop mode in comparison to the FF mode.
Do you remember if ISO 25600 is much worse on the crop mode?
I would like to capture "nature stuff" and many times that would be at low light. At macro levels you'd want details while keeping a reasonable DoF (small apertures).
Also I hope that Sony didn't get rid of the "Clear Image Zoom" in these modern cameras. I love that feature in my A7r II.
He said he had this camera for two weeks. I wish he would have gone into more detail.
Who had the camera for two weeks?
excellent review. ibis still unusable.
footage download link?
There's some confusion in the video, the author doesn't understand what "dual gain" is and thinks it's just "noise reduction", but actually it's something else entirely.
Also the author doesn't understand why there is more detail and better noise in the A7iv, and again attributes the better noise to "noise reduction", but actually this simply because of the higher resolution sensor.
Sorry but this sensor isn’t officially dual native iso, you can see obvious signs of noise reduction on the port capped footage. If it was a proper dual native iso sensor, Sony would be stating it as they do with their cameras that do have it, ie fx9, VENICE, etc. I can assure you I am not confused by either of the subjects you have mentioned. Can you please explain your 2nd point as it’s pretty, confusing?
@@CVPTV He's referring to scaling down the image (7K down to 4K), which also scales down the noise. Many have discussed this as a benefit by potentially making the images look cleaner and sharper... and that is somewhat evident in your controlled test (sharper in this case), though not withstanding the color shift. Not my words, but those of Northrup, Cine-D, among others.
Did you try color matching a7iv with the a7s3? how was that?
Did you watch the video fully?
@@CVPTV Yes, talked about a difference in the raw material. I'm talking aobut color matching them
@@anttiranki3690 anything can be color matched
According to Gerald Undone and his tests on the Xyla 21 the dynamic range is actually a 3rd stop better than the a7siii due to the better noise performance as a result of the high mp downsampling, similar to the a1. The colours in your outdoor tests to me looked better on the a7iV as well.
Interesting… your review shows diff results…
Jason Vong showed it’s actually Noisier video than a7iii.
Gordon Laing showed it has same video resolution/IQ as a7iii.
Not sure what to tell you. Our methodology behind the tests was as follows.
Both cameras set to SLOG3 SGAMUT3.CINE.
Both cameras set to 4K 25, a7 III XAVC-S a7IV XAVC S-I at max data rates.
Both cameras custom white balanced using a grey card.
We then lit ISO 800 on the a7 IV with the aperture around T2.
Using 41% +/- 1 Zebras, making sure our mid grey chip on the Macbeth chart was showing the Zebra.
As we went up in ISO we stopped down the lens.
We then did the same for the a7III adjusting T stop slightly to compensate the difference in exposure we were seeing at the exact same settings as a7 IV on the a7 III.
Jason doesn't explain any of the methodology behind his test and even says it isn't perfect.
I don't believe we mention the resolving difference between the a7 III and the 4 in this video do we, so how does it conflict with what Gordon is saying? Jake
@@CVPTV It would be cool if you reached out to them and figure out who is right! Us mega nerds looking for these particular stats would love it. Subscribed for the quality of this one video alone. Cheers!
Hello. I am watching your reviews and thank you for your work. I would like to advise you on buying 6k video recording equipment. £ 3,000 maximum
The camera is to be used to record music videos and reportages. Thank you.
Can the Sony a7iv record 10 bit video in 1080p ?
Yes
When everyone says that A7IV and A7Siii colour science is basically the same you prove the opposite. Maybe something was off with your A7IV files? Looks awful.
A7S iii records 16bit external
ok and?
I’m concerned by the low burst, the poor lcd screen, the awful roling shutter, the huge crop….
I didn’t understand the part with the charts and the latitude test. Why did the two cameras expose so differently on the same scene even with adjusted lighting? It’s even on the same log gamma curve no?
Also did Sony cripple the a7iv somehow with worse color science as well?
They definitely did not do its rolling shutter justice though, that is some 2013 consumer DSLR video jello effect I see.
Not sure if you understand what the word cripple means. It's pretty evident you don't. a7 IV footage can be easily intercut with footage from the a7s III. 30ms rolling shutter on the Panny S1H circa 2019 and not downsampled from 7K either, so not 2013. 20ms on the s35 sensor of the Pocket 6K, which is nothing to write home about either. 30ms on the Canon R5, circa 2020. You're not funny, maybe choose another career.
@@JonPais a bit harsh there. He asked fair questions. Plus Sony should never give-in to sub par RS...esp. when the previous A7 does 7.8ms at 4k Raw.
@@PC-iv5so yeah someone is very angry about something 😅😂
People are really comparing a 12MP to a 33MP camera and expecting same rolling shutter lol
@@JonPais how much these cameras cost again? Maybe it has something to do with the cooling system and the processor used? Maybe that's why the R5 overheats?
Anyone know how many MP in APS-C mode? maybe 13 I'm guessing?
About 14 if you do the math.
My A7 IV makes a constant faint noise, like a fan working inside. Anyone else?
👏👏👏
And y'all call this _not_ a "full review" [00:46]?!
It's not for our standards - ruclips.net/video/siq2tfEfZqg/видео.html
Great review and feature breakdown / comparison, thanks! Where can I get the hot shoe mounted handle seen here ruclips.net/video/ORIdHKWzG0s/видео.html ?
sucks, it's better to take a video camera for this money
The contrast is ew
On the one hand, I agree, but I think I understand what is going on. Contrast is always adjustable for every Picture Profile, and all the other preset system that Sony provides (I don't know why the include so many overlapping preset systems), so you should be able to match them for most situations if you want to do so. Sony seems to treat the default contrast as relative to the particular sensor in each of their cameras. Slog2 from my a6400 is not going to look like Slot2 from this a7iv, nor like the older a7iii. But if I want to, I can equalize them all to output about the same within limits. Compare that to Panasonic who created VLog-L for the GH5 which has the same slope as VLog, except that it clips early in the highlights instead. Is that better? I don't know. I understand the difference, but at this point, I can't say I have a preference.
useless camera its a very bad upgrade .. so boring
