Thanks sir for making this video possible and nice comparison. The a7c is INSANE!
Hey thanks for watching! Glad I could help.
Awesome review. Miss reviews like this camera comparisons. Now it’s just talk and talk and talk and talk and talk and they don’t show image quality at all. Great job! 👍🏻
Hey thanks for watching! I'm glad you got something out of it. I'm kinda the same. Talking videos are fine, but to me that's not what a review is supposed to be.
great video, thanks for the support. greetings from Chile 🇨🇱
Hey thanks for watching, and for taking the time to say hello!
No difference below iso 6400.
What a great camera the A7c is.
A6400 is a good camera.
Hey thanks for watching! Indeed the a6400 is fantastic for an APS-C size sensor. For me, it really highlights how far ahead of its time that sensor was when it was released 7-8 years ago.
Maybe you should watch the video on a big display with 4k capabilities. On a phone or a ipad it looks like both perform the same till iso 6400. But it is not the case.
At iso 400 you see noise in the a6400 footage. The footage of the A7C looks the same with iso 3200. So there is a 3 stops difference which is a big difference. Plus the A7C gets more light in it because of the bigger sensor.
I also had the a6400 & A6600 and i loved both of them, but the A7C is the better choice in dark light conditions. But both of them have their strengths and weaknesses.
Thats why I switched to the A7C.
@@Krachowsky You are probably right. But then again, who watches RUclips on big screens…
These two cameras are my current A/B cam set up 🙌🏽💯
Great video 👍🏽
Hey thanks for watching!
I'm jealous... Had to sell my a6400 to fund the a7c lol... The a6000 does the job for now as a B for me but eventually I'll probably pick up a new B. Just wondering if I should go with a better photo camera (like say the a7riii) or hybrid (like an a7III) as the prices come down with newer versions on the market now 🤔
@@andreas1701d I feel you. I sold my a6500 to get the A7C 😅💯
I actually returned the a7iii after like 3days and got the a7C instead. I do more video than photo.
@@pauldeshield oh, even though I shoot more photo than video, I still preferred the a7c because of its size. Honestly, I don't find the EVF as bad as people say. It's not great, but I got used to it after about a week or 2.
If they ever made an a7c version of the a7R series, I'd be all over that!
@@andreas1701d yeah, I'd sell both my cameras to get something like that 💯🙌🏽💪🏽
Nice video bro, i like it..
Really useful. Full Frame is full Frame. Hope to get one someday.
Hey thanks for watching!
The good thing is as the years go by and new models are released, we're seeing some great deals on terrific cameras. The a7rII is a great example of an outstanding bargain these days. It's an incredible sensor.
I have the a6400 , i love it and going to stick with it
Hey thanks for watching! I don't blame ya, it's a great camera! Always stick what works best for you.
excellent video
Hey thanks for watching! I'm glad it was useful
The good...very good and detailed comparison. The bad...your scene is a little too well lit at ISO 100 to see any meaningful differences in performance between the two sensors at your typical modern-day high ISO range (ISO 1600-12800). Yes, you do see drastic differences beginning at 12800, but most will not be shooting above that. Try this again, but make the lighting low enough that the image is barely visible at ISO 100. Additionally, what was the point of showing the focus issue (which BTW is not focus breathing since you were not pulling focus, the camera was just unable to lock focus). It's great that you pointed out the EV level at which the autofocus begins to have issues, but the test was about high ISO, not low light autofocus. It would have been better to set the focus manually or locked focus on both cameras to avoid the issue altogether. Good video. Thanks for taking the time to put this comparison together.
Hey thanks for watching, and for the feedback! My goal is to provide tests which are more "real-world" rather than "lab", hence why I don't feel stress tests are relevant in that context ... Having said that, I recognize that I have made some mistakes along the way. It's all about learning in the end!
I thought the A6400 had better colors except over 6400 iso. Great video. Thank you
Hey thanks for watching! There's definitely a difference, and I thought the same but when it comes to skin, the a7c does render it more naturally. Not by much though, and both of em are light years better than the older gen
Lo mas revelador es que la A6400 es una gran cámara por la mitad de precio que la A7C, al menos aquí en Santiago de Chile. Saludos!
¡Oye, gracias por mirar! Lo siento si la traducción es mala, estoy usando Google Translate. De hecho, la a6400 es fantástica. Necesitaba algo de estabilización y un mejor rendimiento con poca luz, por eso elegí el a7c. también es la primera cámara de fotograma completo cuyo tamaño la hizo competitiva con las cámaras a6x00.
1:09 It's totaly me :D
actualy I'm struggling with my choice between a7III and a6600
shooting at night is really a big thing for me, almost the first priority
thank you for this !!
Hey thanks for watching... Hope it helped you make a decision! When it comes to low light, the a6600 wouldn't be bad, but the a7III would definitely be better and worth the extra few bucks in my opinion.
@@andreas1701d Yes I think I will totaly go with a7III.
Wall I just discovered the real time focus tracking and gyro post stabilisatin in video and the a7c in the other hand the a7III if far more convenient with photography
hahaha I'm getting closer ^^
I think a fun test would be doing this same test with the A7C in crop video mode since it has a newer processor and BSI sensor. It would be a glimpse into what a new A7000 series could be like. Do you still have the A6400 footage to use for side by side comparison?
Hey thanks for watching! I do indeed still have the footage. I'll see if I can put that together, though I'll have to find a day/time where lighting is reasonably close so as to not affect the exposure
@@andreas1701d No problem, that's completely understandable. It's just something that popped up in my head after seeing such an ISO difference.
It would be interesting if you could compare A7c + 24mm 1.8 vs A6400 + Sigma 16mm 1.4. They would have approximately similar pov as well as the amount of light on the sensor (1.8 on FF vs 1.4 on apsc). I think then the difference would be smaller, and would bi nice to see that. But of course A7c is much better and would win again but for a price. Thanks for review.
Hey thanks for watching!
In fact I did shoot some with the Sony 20mm f1.8 G and compared it to the sigma 16 on the a6000. The Sigma was my favourite apsc lens, but the Sony 20 + a7c is probably the best camera/lens hybrid I've ever worked with; just incredible image quality.
F1.4 on APS-C is not like F1.8 on FF regarding amount of light and depth of field. F2.0 is nearly the same, actually 2.1 with a crop of 1.5 which Sony APS-C cameras have.
@@Krachowsky Hey thanks for watching!
The depth of field does indeed change on each sensor size, but I'm terms of light gathering f1.8 is identical on full frame and apsc.
I have the Sony a6000. How many stops higher in ISO could I go if I got the a7c, compared to the a6000?
Hey thanks for watching!
The a6000 is very comparable to the a6400 in iso performance, though not quite as good. I'd say the equivalent maximum "usability" is about 3200 on the a6000 vs about 12,800 on the a7c, though it obviously depends on shooting conditions and your subject.
I was planning to do a direct comparison between the a6000 and a7c, so that'll probably help you out more than this video, going beyond just an ISO comparison: sharpness, low light capability, battery life, colours, etc.
I should be able to get that video up in the next few weeks.
Very detail comparision. I'm a Canon user I plan to switch to Sony with a tight budget and I have some question. What is the maximum usability iso on the original sony a7?? how many stops higher the a7 could go? which perform better in the low light condition and is the A7 still worth buying in your opinion? (street and potrait ).Ty !
Hey thanks for watching!
I think for street and portrait, you're going to want something faster than an a7. The AF speed as well as the 5 fps burst will be limitations for sure.
If you absolutely want full frame, your cheapest bet with good AF and a minimum of 10 fps would still be the a7III/a7c.
My suggestion if you're on a really tight budget is the a6000, actually. It'll cost a third of what an a7II would, and half what an a7 would. Spend the difference on glass, even full frame glass if you think you'll go that route some day.
The AF of the a6000 is very quick even by 2022 standards, though it doesn't have the latest real-time tracking, and it shoots 11 fps. Being an APSC sensor, it'll also crop in to give you more reach relative to full frame. It's also much smaller and easier to carry, and has slightly better (though not great) battery life to a similar generation full frame camera.
Arthur R's channel has a really good video talking about the reasons not to buy the a7 today (some of which I listed above). He also has a video comparing all the different generations of a7 cameras.
Let me get you those links...
I'm sure these will help:

I still think the a6000 is a great intro into the Sony ecosystem ;-)... I still have mine going on 6 years now.
I check out the A7 and personally like it because it's a full frame with a SLR style, god I love SLR when shooting Canon DSLR, and it better at high ISO, also gives more cinematic look to the picture, DoF...I'm using a vintage camera from 2002 and Canon 600D so I think I could live with a7 AF :) just personal preference, but overall I agreed with you the a6000 is better . ( A7 and A6000 nearly the same price in my country :)
My final question is the a6300 body worth over 200 usd extra? should I invest in 6000 body and 50mm OSS or a6300 w/ kit lens? Ty for answering my question, subscribed
@@danhkiet19 In the case of going from what you have to the a7, i get it... makes sense. The a6000 will give you roughly twice the ISO performance over the 600D, while the a7 will be closer to 4 times. The a7 will also give you +1 fps burst, a faster mechanical shutter and as you mentioned, both will provide better AF, though the a6000 will be snappier than the a7.
Imho, going for the a6300 over the a6000 only makes sense for the video capabilities of the a6300. The a6300 also has some weather sealing, the a6000 has virtually none. Having said that, my a6000 has seen snow, light rain and temps down to about -20 C without any issues other than faster battery drain when its cold.
What's your total USD budget?
@@andreas1701d My budget is around 550-600$. The a6000 used condition average price in my country is 290$ and A7 is 310$, the A6300 w kitlens is 530$. I could get the A7 and kit or third party lens ( 480$ total) and then maybe upgrade to the 85mm FE, with the A6000 I would get a Sigma 30mm F1.4 (190$) or the 50 Oss (180$). Looking for a camera to work, joy and long term use, thanks again :)
damn, i watched with a lot of curiosity to see how further the A7C goes past ISO 6400. coz i have the A6400 and i know how badly things fall apart at ISO 6400 and beyond
With comparible technology, the rule of thumb is that full frame is usually 2 stops better than APS-C. For instense 3200 on APS-C looks like 12800 on full frame.
Hey thanks for watching!
Good to know 👍
1-1.5 stops. Not 2 stops
is ISO on APS-C the same as a full frame sensor?
Hey thanks for watching! I'm not entirely sure I understand your question.
If you're asking if iso does the same thing on both APSC and full frame, the answer is yes.
If you're asking if both have the same iso values, that is dependent on each camera model but most these days go from about 100 to 104,000.
If you're asking if the quality is the same, I think the video should be able to show you the difference at each iso fairly well.
Or, am I missing the point completely? If so, please provide more detail and I'll do my best to answer.
@@andreas1701d in other words is ISO 400 the same on both sensors? We have to use conversion for lenses and aperture but I never thought of converting for ISO. Some jobs I do want a certain ISO but they are referencing full frame iso. know what i mean ?
@@funkyboogiee it's important to note when you're calculating equivalence of aperture, it only relates to depth of field. An f1.8 lens will let in the same amount of light on APSC and full frame; in other words, exposure will not be different.
The same goes for iso. The "brightness" of a given iso will be identical on the two sensors. What will change is how much noise each sensor produces at that given iso.
@@andreas1701d for real estate; Full Frame folks are shooting f/8 iso 400, at the company i work with. on my Fuji XT4 aps-c i have been shooting f/11 iso 400 on my 10mm lens. just trying to make sure i dial it in the way they are doing with ff.
@@funkyboogiee I actually just shot a video today comparing the exposure between APSC and full frame. Should be out by Monday morning.
If f8 and iso 400 is the correct exposure for what you're shooting, that shouldn't change no matter the sensor.
I wouldn't worry too much about iso 400. Modern apsc cameras should have no trouble giving you clean images at that value.
i want see comparison between zv e10 vs a7c
Hey thanks for watching! I'll try to get my hands on a ZV E10, but it should be very similar to this in terms of iso performance. The sensor is identical to the a6400
i wouldn't expect any different results from the ones above since the ZV e10 has the same same sensor as a6400
