@@k2blades540 So what is better about the Otus then? Sincere question here if I'm going to consider spending 3x as much money. Just when I hear people talk about the Otus, they always talk about how sharp it is. Sharpness seems to be the selling point for the Otus, so this seems to disrupt that in a big way.
This may be one of your best episodes. Compiling your standard effortless breakdown of technical data with testing and real world shots really rounds out this review. Solid job sir.
The combination of the straight face while saying "I'm Gerald Undone and I'm not wearing pants" was too much for me to keep my sip of coffee from trying to shoot through my nose! Thank you to the Gerald Undone fan that suggested that line. As for me....I'm wiping hot coffee off my keyboard! EDIT: The cinematic theme and music choice are awesome. I think my favorite scene was the photography of the yellow dandelion looking weed. Beauty in an auto graveyard! So happy to be subbed, I love this stuff!
I never took the time to understand the MTF charts and wasn't expected to learn about them on this video. Thanks! Your explanation are technical and easy to follow! The best of two world :D
Hi Gerald, after watching this video i returned Sigma 35mm 1.4 art and purchase 40mm 1.4. When i tested the sharpness at store today I had A9 on tripod and took shots with 35 and 40. Forty 1.4 was blowing out 35. I didn’t think i would make much difference in sharpness on A9
I bought this lens a few months ago. Reason? SHARPNESS across the frame is number 1 for me. This a great lens for ASTROPHOTOGRAPHY, PORTRAITS and Architectural Photography.
Great review of this lens. It was the perfect blend between the science and practical use of how most will use the lens. Thanks for continuing to put out great content, without needing 30 minutes to do so.
It shouldn't come as too much of a surprise that the 40 is so great considering it's essentially the optics from Sigma's 40mm Cine lens re-housed and given an autofocus motor. It also makes its cost a pretty killer bargain for what you get.
Super impressed with the nerdy in this video. I’d love more in depth explanations of super nerdy camera stuff here. Really enjoy them and this content really helps me feel like I know what I’m doing rather than making educated guesses, if that distinction makes sense. 👍👍
Kudos on being thorough. When you mentioned the issues with the close focusing, my first thought was the close focusing distance, and voila, you included that. Great video, as always!
This review was so helpful in convincing me to buy this lens. I got it for Nikon and it’s absolutely unbelievable. Huge value for money now that it’s been out a few years.
I decided to pair this with my Z 6 at xmas and it is RAZOR sharp! Sharpest lens I've ever owned and the sharpest before that was the 300mm f4 IF-ED and 70-200 f2.8 VR1.
Thanks for the excellent explanation of the MTF charts. My budget director, (my wife), allowed me to get the 55mm Otus a few years ago. It's sick that the 40mm was in Otus territory on the chart. Sigma has done a nice job with their Art lenses for Canon in my opinion. The larger Canon bodies feel more comfortable in my hands since I am use to dealing with heavier lenses which kind of feels better balanced on the larger bodies. I add grips to my bodies because personally I feel more comfortable when I use them with heftier lenses.
@@geraldundone I Love it. It was definitely worth the investment. With Canon's focus confirmation, I have no issue with it being manual focus and in my opinion, sharpness is second to none.
I think I’d love this lens over my Art 50mm . I shoot live music video and photography. The 50 is ok just a little tight , flares super bad in live music shows . This kills the pics and make them unusable. But don’t know if they made that any better. But I like the 28mm and 40mm lenghts best for live music
Very late to the party but just to nitpick on one thing: Depth of field is the exact same for both shots, the only difference is that the 40mm has a wider entrance pupil when shot at same aperture, therefore it creates larger blur circles, and with the perspective difference (aka compression) of the background, this appears more blurry.
Who is it? & What is the track title @@geraldundone? It sounds like Daft Punk from Tron Legacy P.S. On the lens size... It looks big enough to have a tripod collar
Personally, I'll take size over extreme sharpness. That's why I'll stick with the 55mm 1.8 (281g) over the Sigma 40mm(1.2kg), even though the Sigma crushes it on the MTF charts. I'd really like to see the MTF chart on the Sony 24mm GM. I'm renting it at the moment, and its corner to corner sharpness is insanely good, even when wide open. I'm sure it won't be on par with the Sigma (what is), but it's a size that I can take hiking without hating myself :)
I switched to the Nex5, 6, A7 and A6k as soon as they came out cause I couldn't bear the weight of my A300 with an 17-70 anymore. So in my eyes this is for studio use only but impressive.
I ordered this lens solely because of this video lol... And I had the 35mm (which I adore - I always said I'd never sell it but no point keeping both)... Thank you for the awesome review!
This might be a stupid question; I know bokeh quality is extremely subjective, but would you say that rounder/more perfectly circular bokeh is generally more desirable? One thing I noticed in your test was that the 40mm has more lemon shaped bokeh balls, and that would put me off from getting a lens, personally, while the less-sharp 35mm has almost perfectly round bokeh. What are your thoughts on this?
I think that for some purposes the rounder bokeh is more suited, but that can also make a lens seem kind of lifeless in certain scenarios. Lenses with abnormal bokeh can be more interesting and provide more character, but it would depend on the look you're going for and the subjects you're shooting. No wrong answer.
that size is crazy, I own the 35 Art Canon mount, and it works ok adapted to my A7r lll, but the 35 is already a heavy lens, the 40 seems like amazing image quality, but I would not buy it because of the size and weight. and if you are not pixel peeping you would never notice the difference over the 35 with the image quality.
The only think that would make me buy this is if its compatable with my Anamorphot-50 1.33x. Because the longer the lens the less sharp it looks through the anamorphic adapter. My 85mm 1.4 looks so blurry because of the size of it.
I want a good lens for filming RUclips videos, In the same scenario as what you have. And 40mm is kind of the most realistic focal length I can get in my small room. And I wanted one with f1.4. Because Sony dont have a lens around 40-50 that can do f1.4 that is a gm, I think this would be the best one to use, even though it’s big it will be on a tripod most of the time
Great video. Quick question, I have pre-ordered the Leica SL2 and I'm trying to decide if the Sigma 40mm would be a good fit. Your thoughts, please. Also, do you recommend any other lenses? Thanks.
I tested this lens in shop. I was so surprised at its performance. I initially thought it was just that the primes are better than my GM zooms. But then again no other primes are as close other than the GM and art. But end of the day I put it down. It is just so huge and heavy. I felt like I'm going for an overseas body building trip with it for just a 40mm.
The thing that interests me is that it's a fast 40. I like 40, I shoot about 50% available darkness. But, heavy. Bus, there's not a lot of competition in fast AF 40s. There seem to be radically conflicting opinions about the vignetting on this -- some sites complain about excessive vignetting, you report that it's good on the charts. What have you noticed in practice?
There is definitely some at f/1.4 and it's significantly improved by f/2.8, but I haven't found to be an issue. And vignetting has always been pretty easy to fix.
Sigma has published the 35 mm f:1.4 for the L-Mount. It is dust and water resistent. Have they changed the optical quality of this glass? The difference in price between this 2 lenses is big and I wonder, wich one to buy.
Had Sigma 40mm, was only beaten by a Lens multiple times more expensive - Zeiss Otus, only marginally, no other Lens delivered the sharpness & resolution, at that time. Obviously Sigmas downside with the _ART series_ is size & weight. *I switched to the 28mm Art for Landscapes & also 24-105mm Art, both are beautiful. I prefer Lenses with Aperture rings & less bulky but its a compromise.
I moved to sony. On the A7SIII it could be a good choice for high quality videowork. But one question is unmentioned: who loud are the motors while focussing in AF-C? Vor video it is a dealbreaker, when you could hear the motors constantly working.
I don't know about you, but considering the increased sharpness in this lens and the types of example photos you shot with it, it seems like a very good choice for macro photography?
Hey Gerald.. So if it's only being used for Video purposes would you say this is worth the 50% increase in price over the 35mm? I am looking for a semi wide lens (28-50mm) for shooting interviews indoor and outdoor that's faster than 2.8. Would this be worth it over the 35mm or the 55 1.8 Zeiss?
I wouldn't say that it's necessary. Generally we have more sharpness than we need for video even up to 4K. If you were shooting 8K then you'd probably see a noticeable difference, but I'd say you can get away with a smaller lens. I'll probably still use the 35mm more often.
I really want to get this but I was really let down from my Sigma 20 art for the E mount. It hunts way too much for video. Is this an issue with the 40? The 20 is unusable for video
If there's that much of a difference between art lenses, how much of a difference is there between the top end and consumer or prosumer level glass? How does one know where the "good enough" point might be?
Well, I suppose that would always just come down to the right tool for the job and what you and your audience is happy with. But there is quite a bit of variance in lens quality out there and price doesn't always mean everything.
GERALD WENT OUTSIDE!?!?! Woah, I gotta admit I've been waiting to see you outdoors doing some of these tests, I definitely got excited. Amazing content as usual!
Hey Gerald :) Could you please make a video about how knee, black level etc affects image ( i have an A7 III) ? trying to create a grade with as much highlights preserved as possible, with a little Arri alexa tint for HLG 3. Thanks :) I love your technical in depth videos!
Don't touch any of it, as you won't get more dynamic range. Fix contrast in post. Consider the Leeming LUT for colors (and see the Leeming LUT Facebook group for technical advice).
Here's a helpful article from the Sony Help Guide on it that will probably answer all your questions: helpguide.sony.net/di/pp/v1/en/contents/TP0000909110.html Personally, I don't change those settings, I do it all in post.
Hello Gerald, once again a crazy good video. If you have a bit of time, this comment will be maybe a little bit long, but maybe it gives you an idea for the future. Watching the pictures you took at 06:33, 06:41 and so on, i assume the raws were imported into lightroom and not really tweaked afterwards. It seems to me that Lightroom always does a bad job at raws from the sony A7iii, adding sharpnening that i find myself removing everytime because, to me, A7iii with 90mm macro 2.8 is sharp enough, would rather a use a bit of luminance most of the time. To me, it's lightroom related because it seems CaptureOne is doing a better job straight out of the box. So my point is (ouch i rambled again), is it really so in your opinion ? Did you notice that kind of thing too or is it just me ? DXO and Darktable are also alternatives. Well hope you'll get an idea for a superb video ;) Thanks for the great content
Hey! I've heard a similar complaint from others. I personally don't have any issues with Lightroom and Sony. Lightroom does have settings automatically in place in the detail tab that perhaps people don't realize. If you put those to 0, it shouldn't have much in the way of unwanted sharpness. But maybe it's just a personal preference thing. Appreciate the kind words and the suggestion. Cheers!
@@geraldundone exactly, Lightroom has presets and I'm not sure people realize it and know how to change them so it would be auromagically applied when importing new raws. To remain on sharpness settings, those are not on 0 when you start using Lightroom with Sony a7iii, and if you compare jpegs from camera and raw from Lightroom, jpegs were better looking. Was strange to me as a beginner.
Excellent info as always. Any way to compare the 40 to the Sony 24-70GM. I'm still "on the fence" about primes vs GM zooms sharpness-wise. Is the difference now only in the speed of the lens?
Thanks, Matthew. Generally there is a considerable improvement in sharpness with primes. Especially if you consider that primes are faster and lenses often perform best stopped down. If you stop a f/1.4 lens down to f/2.8 to match a zoom, it usually blows it out of the water. You have to give something up to get the versatility of a zoom. Now telephoto zooms on the other hand can be sharp and versatile, but they cost a fortune.
Hmm. This one? bit.ly/2TV5sYT It works on my end. Here's the long version: artlist.io/artlist-70446/?artlist_aid=GeraldUndone_376&GeraldUndone_376&GeraldUndone_376
Amazing video! What a crazy lens! Would you consider buying this lens to use it for manual focus video only? Like a « cheap » substitue to their 40mm T1.5 cine lens? Thanks a lot Gerald
Thanks so much! Yeah, generally the Art lenses make for good budget alternatives to cine lenses. People use them all the time for that. The only consideration is the focus breathing and the build quality, but other than that, you're getting very similar quality for less money.
Gerald Undone thanks for your answer Gerald! Yes I’m not worried about the optical part of the lens because I’m pretty sure it’s not far in quality from its Cine Big Bro’ The focus throw is my concern actually... but I plan using it with lots of gearing on my follow focus. What you think? Cheers ✨
The Sigma is definitely sharper and a full stop faster, but the Batis is only 361g, so it's much lighter. The Batis is also a very strong optical performer.
Gerald Undone do you think maybe yours has slight QC issues? Mine is tack sharp wide open and yours looks softer than what I've seen from most copies of the lens.
for this kind of performance, im surprised it doesnt cost more
it's better than the Otus for 1/3 of the price and it has AF!
Thanks for sharing your point of view!
It's sharper. Nothing else is better. Sharpness is highly overrated.
@@k2blades540 In your universe, maybe price and having AF doesn't matter, but that's like, just your opinion man.

Also the longer tripod plates just prevent you from turning focus rings in many cases
Simply use a L-bracket, very useful on those compact Sony bodies anyway :-)

@Gerald Undone Would be great if you could do a comparison with the Voigtlander 40mm f1.2. Im right now thinking which one to buy for my A73
The only think that would make me buy this is if its compatable with my Anamorphot-50 1.33x. Because the longer the lens the less sharp it looks through the anamorphic adapter. My 85mm 1.4 looks so blurry because of the size of it.
Do you think the battery grip would help balance the body/lens weight difference?
I bought it for 560 euros on black friday and its awesome :D

"I'm Greald undone and I'm done"
That's with the a7R3 right? Gotta take advantage of that sharpness!

What does the MTF look like on the 50mm & 85mm and 56mm sigma art?

I wouldn't say that it's necessary. Generally we have more sharpness than we need for video even up to 4K. If you were shooting 8K then you'd probably see a noticeable difference, but I'd say you can get away with a smaller lens. I'll probably still use the 35mm more often.
@@geraldundone Appreciate the reply man. I've been trying to decide for a while now. And I really want a fast piece of glass. Thanks again
Excellent,thanks! One thing missing would be a quick Astro shot wide open please?
That's so fckn sharp! Those photos in junkyard blown me off completely. Sigma really hold up their Art badge high in the sky with this lens
Great video! Loving the technical talks haha!
🙏😃
I really want to get this but I was really let down from my Sigma 20 art for the E mount. It hunts way too much for video. Is this an issue with the 40? The 20 is unusable for video
I haven't used the 20, but I haven't had any issues with the 40mm.
If there's that much of a difference between art lenses, how much of a difference is there between the top end and consumer or prosumer level glass? How does one know where the "good enough" point might be?
Well, I suppose that would always just come down to the right tool for the job and what you and your audience is happy with.
But there is quite a bit of variance in lens quality out there and price doesn't always mean everything.
I was considering the 50 1.4 from Sigma, not sure whether to go for that or this new one. Comparing with the 50 1.4 would have helped better.
The 50mm is very similar to the 35mm, so most of the stuff I said here stands.
Fantastic review!
Hi Gerald...have you heard of the Batis 2/40 CF? any comment on that ?
I have. Good lens. Not as fast or sharp as the Sigma 40mm, but considerably lighter and a decent option.
GERALD WENT OUTSIDE!?!?!
Woah, I gotta admit I've been waiting to see you outdoors doing some of these tests, I definitely got excited. Amazing content as usual!
It was cloudy enough that the sun wouldn't turn me to dust. 😜
Hey Gerald :) Could you please make a video about how knee, black level etc affects image ( i have an A7 III) ? trying to create a grade with as much highlights preserved as possible, with a little Arri alexa tint for HLG 3. Thanks :) I love your technical in depth videos!
Don't touch any of it, as you won't get more dynamic range. Fix contrast in post. Consider the Leeming LUT for colors (and see the Leeming LUT Facebook group for technical advice).
Here's a helpful article from the Sony Help Guide on it that will probably answer all your questions: helpguide.sony.net/di/pp/v1/en/contents/TP0000909110.html
Personally, I don't change those settings, I do it all in post.
Hello Gerald, once again a crazy good video. If you have a bit of time, this comment will be maybe a little bit long, but maybe it gives you an idea for the future.
Watching the pictures you took at 06:33, 06:41 and so on, i assume the raws were imported into lightroom and not really tweaked afterwards. It seems to me that Lightroom always does a bad job at raws from the sony A7iii, adding sharpnening that i find myself removing everytime because, to me, A7iii with 90mm macro 2.8 is sharp enough, would rather a use a bit of luminance most of the time. To me, it's lightroom related because it seems CaptureOne is doing a better job straight out of the box. So my point is (ouch i rambled again), is it really so in your opinion ? Did you notice that kind of thing too or is it just me ? DXO and Darktable are also alternatives. Well hope you'll get an idea for a superb video ;) Thanks for the great content
Hey! I've heard a similar complaint from others. I personally don't have any issues with Lightroom and Sony. Lightroom does have settings automatically in place in the detail tab that perhaps people don't realize. If you put those to 0, it shouldn't have much in the way of unwanted sharpness. But maybe it's just a personal preference thing.
Appreciate the kind words and the suggestion.
Cheers!
@@geraldundone exactly, Lightroom has presets and I'm not sure people realize it and know how to change them so it would be auromagically applied when importing new raws. To remain on sharpness settings, those are not on 0 when you start using Lightroom with Sony a7iii, and if you compare jpegs from camera and raw from Lightroom, jpegs were better looking. Was strange to me as a beginner.
Do you have any Sasquatch footage? If so it would be cool if you would share it.
You lost me...
@@geraldundone Naah. The Sigma is WAAAAY to sharp for Sasquatch/Bigfoot pics. They have to, by definition, be blurry and OOF.
lol, that's true.
Sigma 35 mm 1.4 is flawless,40 mm 1.4 is fabulous.
is it safe to say the same thing about the sigma 28mm art as well?
Love your videos!
Excellent info as always.
Any way to compare the 40 to the Sony 24-70GM. I'm still "on the fence" about primes vs GM zooms sharpness-wise. Is the difference now only in the speed of the lens?
Thanks, Matthew.
Generally there is a considerable improvement in sharpness with primes. Especially if you consider that primes are faster and lenses often perform best stopped down. If you stop a f/1.4 lens down to f/2.8 to match a zoom, it usually blows it out of the water. You have to give something up to get the versatility of a zoom. Now telephoto zooms on the other hand can be sharp and versatile, but they cost a fortune.
Thanks for the thoughts and info! You da man!
Hey, bro, the link for the music is not working, or the problem is with my device?
Hmm. This one? bit.ly/2TV5sYT
It works on my end.

How about for Aps-c user? also good?
Amazing video! What a crazy lens!
Would you consider buying this lens to use it for manual focus video only? Like a « cheap » substitue to their 40mm T1.5 cine lens?
Thanks a lot Gerald
Thanks so much! Yeah, generally the Art lenses make for good budget alternatives to cine lenses. People use them all the time for that. The only consideration is the focus breathing and the build quality, but other than that, you're getting very similar quality for less money.
Gerald Undone thanks for your answer Gerald!
Yes I’m not worried about the optical part of the lens because I’m pretty sure it’s not far in quality from its Cine Big Bro’
The focus throw is my concern actually... but I plan using it with lots of gearing on my follow focus. What you think?
Cheers ✨
For me, it's between this and the Zeiss Batis 40mm/2...both are pricey but which is sharper?
The Sigma is definitely sharper and a full stop faster, but the Batis is only 361g, so it's much lighter. The Batis is also a very strong optical performer.
@@geraldundone sigma it is, then. For me, sharpness is critical... Thanks for the reply!
Have this 40f/1.4 on the d850 and it just is amazing @1.4 and @f/2.2 its insane
Out of curious, did you get your 35mm Art in the original shipment when then lens was released?
Yeah, probably. I got it as soon as they became available for E-mount.
Gerald Undone do you think maybe yours has slight QC issues? Mine is tack sharp wide open and yours looks softer than what I've seen from most copies of the lens.
