Excellent analysis. I upgraded from the r2 to the r4 as soon as the r4 was announced. Detail for fine art - architecture - macro - landscape is a huge increase. hence for anyone requiring the extra resolution the R4 is a no brainer. Also because of the high mp each prime lens becomes more versatile because of cropping & on super 35 mode in still one is still getting 26mp. I am not into 10bit so video is fine for me & I can use the stills for a lot of animation & panning in viedo processing. For those requiring more of a hybrid camera the 74 is the choice. The price difference is not that much now - given the r4 is an older model & also available 2nd hand
Sony A7RIV/A7RIVA are the BEST for still Photography if you want fx an image of a Landscape in a very large print ! I do 99.99% of my focusing manual and I NEVER use video, so I cannot see the point with the A7IV, I think that the A7IV are too expensive, much more expensive than the A7III was. I have a Sony A7RIV and a Sony A7RIVA, I love them very much and I can very highly recommend them !
You will not see a difference in prints. Check some guy his youtube video he compared 12MP A7SIII prints with Hasselblad 100MP prints. Most people thought the Sony was sharper.
I tested both cameras (with Sigma ART 24-70mm F2.8 and Sigma ART 35mm F1.2). The price was the same. A7 iv had everything better, except the resolution. I finally bought the A7 iv, but I am still not convinced that it was the right decision. However, there's one more thing. A single pixel on the A7 iv is better than a single pixel on A7R iv. This was especially apparent in poor light conditions. So although the A7R iv has two times more pixels, the amount of the details it captured was not two times more, because of the noise and also probably because of the limitation of the lenses and easier stabilization of the A7 iv. Depending on the conditions, it was a little more (but not two times) or the same in poor light.
According to the Hybrid Shooter and others, the a7RIVA has improved AF performance versus the a7RIV. Not drastic, but much improved. This improvement was silently implemented by Sony.
Great video! I Currently own both and can attest to these results. However, not requiring a ton of video capabilities, I will be returning the A7IV. I shoot a lot of wildlife (mostly birds) and you cannot beat the amount of crop you receive with the RIV. Buffer speed hasn't affected me as much as I thought it would. I'll keep this until hopefully an RV comes out with CFExpress, lossless compressed, and bird eye tracking. Then this camera will be perfect for stills.
Good review Mathieu! One of the first reviews where the autofocus of these cameras is compared with practical results. Was looking for this kind of comparison.
Top notch as always, even when you are not really interested in a particular camera. It's always nice to watch a well done review in a world so full of shills.
Can anyone chime in, why would you spend the extra on the A7R IV over the A7 IV in a real world use comparison, is the extra megapixel really worth it for all the workflow downfalls of it? The give and take between two seems insanity inducing.. Great comparison!
Just saved me a $1000 going with the a7 iv. Birds are my passion so just the bird tracking alone seals it. I had the same experience buying a pair of Swarovski binoculars deciding between the much more expensive EL or Pure lines vs the more affordable SLC. I checked out both and qualitatively I simply couldn't tell the difference in viewing resolution so I went with the 15x56 SLC which is not only much bigger and some may say not the perfect birding size but it allows great wildlife and landscape viewing at a far greater range (and again I saved $1000)
I think Sony messed up by not allowing the A7R4 to lower the raw shooting capability to 40, or lower. It should have offered at least 3 settings. Csnon has this in most models I know of.61mp maybe very important for many situations, but not all, and its important to be able to use it with lower resolution , specialy for faster shooting or more room, etc.
Thank you for the Video - i found it very helpfull. I have a 7III and probably i will buy a second camera for using for events. Then i didn't need to change the lenses during the event. The price is nearly the same (A7IV 2.800 Euro, A7RIV 3.300 Euro) - espacially when I consider, that the CF-Cards for the A7IV are at a very high price. Using 2 CF-cards in te A7IV for a backup isn't possible, when using 2 SD-cards the buffer of the A7IV isn't big enough: the A7RIV can take more (and each one with nearly double MPs) frames as the (newer) A7IV. I think, for me the A7RIV will be the better camera.
Thanks for your work! Ive spent a lot of time searching useful info about A7RIV amd A7IV specs. You make it easier to decide but still im a bit confused so ill ask your opinion here. Im shooting only birds, BIF and still but after a lot of research im still unsure. Plan A: A7IV with 200-600 + 1.4 TC Plan B: A7RIV with 200-600 +1.4 TC Which one do you suggest and why? Thanks in advance!
I've just purchased a Sony A7R IV for £1500 brand new. I don't know too much about these cameras, but didn't want to overthink things, I haven't had a DSLR for over 10 years and am excited to be getting back into Photography. Yes, it's now a 3 year old camera, and there will always be better and better cameras, but for the price, and the kind of photography I will be doing (Landscape and maybe Street Photography) I am more than happy with my purchase. I will be buying a 16-35mm f2.8 and think that'll all be a nice set up. FYI, my previous DSLR was a Nikon D700 which I sold around 2013 (and which cost me £1700 brand new when I bought it in 2010 - so not bad price I paid for the A7r IV me thinks :) ).
I bought A7 IV with intend to replace A7R IV and ended up sold A7 IV instead. A7 IV auto focus is better and 33MP is more enough but there is one show stop issue is RAW file not supported by Apple IOS. I don’t like flip screen anyway, so decided to keep A7R IV and no regret.
If i am using A7R2, should I upgrade to A7R4 rather than A74? I am enjoying with A7R2 42mp but its focusing performance lag behind recent mirrorless camera. Especial when shooting kids
If you want to take high res photos of stills (landscape), you can always make panoramas by stiching photos. With my Sony A7III I could easily create high res prints to A2. The AIV will even extand the capabilities. And if you are a hobby photographer....how will you argument the higher res?
The resolutions are very similar so the comparison are in video and speed and the A1 is simply better. My A7R IV is an unreal camera, but using it for fast action it is simply too slow, I set animal eye tracking and it locks onto the subject and gives me the eye box, but even with a slow moving subject it back focused every shot because the focus simply can not keep up. This is with a very shallow depth of field though with a close subject, with the subject further away it nails focus on every shot.
Funny I actually like the older color palette more, mostly for portraits. The new colors seem too yellow I comparison. Sony should stop tweaking the colors indefinitely and finally adopt their own signature.
Great comparison thank you. I am about to upgrade my 7iii but recent videos like this are making me lean towards the Riv rather than the iv I originally planned, mainly due to the resolution and the abilty as a prime lens user to heavily crop. I like the idea of the better screen and evf too. My biggest concern is file size though. I have an x360 HP with 2tb of space and 16gb RAM. So, plenty of space but will I face long delays in Lightroom? Any thoughts out there? Oh, I never use video.
Hmm, not sure honestly, I'm not an expert when it comes to computers. I can only compare with my older Macbook Pro (2018 model), and the A7R IV files worked fine in Lightroom. I suggest you ask in forums, hopefully you'll find someone that uses the camera with the same computer you have, or one that is comparable in specs.
Full credit to Sony in making 4K video look like 1080p . I don’t think many people care as long as they have 2 card slots and a big grip and a full size HDMI and a sixty fps without a crop and dynamic range 15 stops and AI autofocus,nobody cares about the actual resolution or photos which is why we buy an expensive camera and lenses.
Thank you for such a great review! Can I ask which one you would recommend for someone just beginning their photography journey? These are the 2 I’m deciding between, happy to invest in GM glass but undecided on the body due to high MP and file size but also is it worth the extra $ with the features on the IV for someone who’s new? 😅
Don't think about it too much, and get the one that costs less. If you're just starting in photography, either of these are more than you need. Enjoy the journey and the learning process, I'm sure you'll have a great time either way.
Thank you Mathieu for your reviews!…could you speak to the speed of actions like waiting to review a picture, lag times after adjusting exp compensation or start up speeds for both… I have an a7r2 and it is frustratingly slow in these areas… and want to avoid that problem if i upgrade.
Start up can still be a bit slow, but I'd say it has improved over the 2nd generation. I haven't noticed any lag time when adjusting exposure compensation, or at least not to the point of bothering me.
Thank you for this video! I'm an influencer and shoot with the Sony A7R mark 2 and hate the slow autofocus. Unfortunately, I still don't know whether it's A7 IV or A7R IV. I rely a lot on resolution but also on fast autofocus because a lot of images have to look authentic. Can you give me a tip which camera would be better?
Thank you for your hard work you did an amazing job 👍 but I still cannot decide which one to buy especially with the R currently on sale on B&H and then RV is expected to be announced soon 🤦♂️
Not sure when the R5 will arrive. It depends on where you priorities are: - image quality with lots of details? A7R IV - more advanced video, better AF? A7 IV Personally, I think the A7 IV covers 99% of our needs.
I have zero experience with underwater photography so I’m probably not the best person to give you an advice on this. I think they can both do well, considering the investment for a good housing and a good lens, perhaps it makes sense to get the A7 IV. But other people might be able to give you more information.
I'm thinking now that such good image resizing programs are available, there is no need for higher megapixels unless ones workflow is concentrated on super high res photography and videography
my apologies you did briefly i m sorry . thanks for the information. i was undecided about which version to get , now i will just get the a7r4 thanks a lot
Image quality is the same, whereas the A7R V has more to offer for video (10-bit internal recording, 8K, 4K 60p etc.). The autofocus of the mark V version is a step up, the EVF is larger with more resolution, so all in all I would say the A7R V if the better choice.
Great comparison, thanks! Do you have any figure for the shutter life expectancy for the A7iv? I know the A7R series is rated for 500.000 shots but I can't find any info about the A7iv.
As always a really informative review! Nice to see that you guys own films by the great filmdirectors of the past. I sometimes feel like a dying breed in these Netlflix ages...
Edit: some grammar errors! @@cjtubongbanua2367, it depends on your use case. If you need high resolution work and need to crop in, A7R4 but buy it used on Ebay or aftermarket. You can get it about same price as new A74. I got mine for $2600. If you’re a hybrid shooter and need both stills and videos, then A74. I also have both of them and use them as the design was intended for. I see a lot of users use it not for its strengths but for its weakness. Part of this to blame is Sony Marketing doesn’t do a good job to provide a buyer’s guide for their customers so they leave it to mostly user errors to determine the narrative. For example, why would you buy the A7S3 for stills. But if you shoot only video, it’s A7S3 or FX3? For sports or wildlife where subjects or animals are fast moving, you need the A1 (if you have the money) or the A9i/9ii, not the A7R4/4a. Good luck!
I have the A7rivA and use it mostly for wildlife. Looking to switch to the A7IV asi like the articulated screen and it has better autofocus but I'm unsure if I'd miss the pixels.
I have both and use it for the same thing. Don't do it. The RIV wins hands down. The autofocus does not compensate enough for the pixel loss and dynamic range. Just my opinion.
If you use a zoom lens like 200-600mm with a TC then the A7 IV is the winner since the AF will be superior. But ofc the RIV has more cropping capabilities. For prints, even 12MP photos can be printed on huuuge formats. So 33 is more than enough.
I feel like instead of only discussing MegaPixels in relation to image quality and printing we should also talk about the sensor and the end result regarding sharpness and overall quality. 33 is plenty. Cropping in is fantastic. But some cameras just take better images.
@@nubscrub A7 IV has better ergonomics, updated colors, faster af, faster storage, flip screen and better video. A7RIV has more pixels, but 99% of the people don't need that.
I did the same almost as you did. I received the 7R4 then viewed this video, then decided to return it untouched (I never opened the box) for exchange of A74 with a 80G CFA bundle, which will be arriving hopefully tomorrow. Cheers!
I own both. The A7RIV is better ONLY if you need the resolution. Oddly enough the A7RIV can shoot 10fps & the A7IV can't (that's unacceptable). The insanely large files the A7RIV create are unusable unless you're a pro, you can't use them online without severe downgrades. The A7IV is AMAZING in lowlight, the A7RIV is absolutely terrible.
Stop looking at 100% magnification looking for noise and you'll be fine. One camera cannot be amazing and the other absolutely terrible. That is complete nonsense, you are not comparing a FF and a m43 sensor...
Light Image Resizer. Compress the images, and you're done. I compress all images on my laptop. Quality is pretty much the same, file size is reduced by 80 to 95%, depending on how much I like the image =).
Thank you Mathieu for the excellent analysis. A friend of mine is offering me the A7R lVa in a very low price and he didn´t use the camera. Here in Argentina it is too expensive to buy one. I´m a film maker not a photographer. Questions: 1) Did you record with the A7R lV in 4K in a place where the temperature was 30ºC? You compare both cameras recording at 21ºC I remember. 2) If you use the A7R lV in 100fps ¿does the sensor crop the image? It is happens to me with my A7 Sll.
Have you encounter eye af focussing on the eye lash? Mine always focus on the eye lash not on the iris. Also the LCD freezes sometimes. Is it possible that firmware update would fix this in the future? Thanks
That’s a shame. I never had a problem with my copy of the A7 IV, even before the firmware update. I know about it because other people asked me about this, and also DPreview wrote about it. Not sure why some users are affected. Could it be related to certain lenses, perhaps?
15:20 like most TH-camrs you assume we can see a IQ difference at 100% but most of us watch this on a tiny 720p mobile phone screen. You need to zoom in 400%
what about shutter lag. A7iii was a stinker for that, lab testing said it was good but in the field it was fantastic at snapshots of the past. Great for American politics
What amazed me about your comparative review in reference to the Sony a7iv, there was NO mention of OVERHEATING when shooting video for an extended period of time. Many other reviewers & recent owners have complained about overheating issues of the Sony a7iv. Have you really tested this camera in real life shoots, or are u just going off printed specs from Sony? Please let us know.
You’re wrong. I DO mention overheating and also SHOW YOU the camera’s LCD with the recording time exceeding TWO HOURS. How about you REALLY watch the review, instead of questioning if I really tested the camera?

Excellent analysis. I upgraded from the r2 to the r4 as soon as the r4 was announced. Detail for fine art - architecture - macro - landscape is a huge increase. hence for anyone requiring the extra resolution the R4 is a no brainer. Also because of the high mp each prime lens becomes more versatile because of cropping & on super 35 mode in still one is still getting 26mp.

I recently had to decide between these two. I went for the R ivA because I don't shoot video and ultimately, image quality is king.

This is why you don't have any video....
Much more expensive is only $500, that's not "much" expensive.
I heard about dust issue of RIV/RIVA, is it ?
@@iamrevel1430 I have been using the A7RIVA since the start of the year and have not had any dust issues, at least not in my personal use case.
You will not see a difference in prints. Check some guy his youtube video he compared 12MP A7SIII prints with Hasselblad 100MP prints. Most people thought the Sony was sharper.
All of us camera geeks are lucky to have understanding wives who put up with our hobby.❤
This is an excellently produced video. It tells us all we need to know to compare the two cameras in an easy to understand format. Thank you.
I’ve watched one minute of this video, and it’s already by far the best comparison I’ve seen of these cameras 🙏
I tested both cameras (with Sigma ART 24-70mm F2.8 and Sigma ART 35mm F1.2). The price was the same. A7 iv had everything better, except the resolution.

Just have to ball up on it then go hard on 2x.
Hi. Could you answer me?
If we set resolution of A7riv to 15mp
(4 pixels to 1 pixels) does it sharper than
A7iv pixels much?
If you downsize the rIV in post it is better than the IV...lol
According to the Hybrid Shooter and others, the a7RIVA has improved AF performance versus the a7RIV. Not drastic, but much improved. This improvement was silently implemented by Sony.

Sony a7r IV for the same price as A7 IV. witch one would you take?
I, from Iran, looked at this review before buying. It was really great.

@@MathieuGasquetMirrorLessons 6500$ later, they could have added some lenses :-)
Great comparison , comprehensive , well structured & covering very important features , very useful , many thanks
Thank you!
At the end I think A7IV as A7III in the past is the best cameras at their time. Amazing combination for still and video.
Great review! This helped me make up my mind. Excellent work.
So which camera should I get for video
A7 IV: it has more to offer like 4K 60p, 10-bit video, etc
good review. i get all the answers for my questions. thanks a lot
Thank you for the video. Very good. I will end up owning both so it’s helpful on the best way to deploy them for various projects. Take car

Plan B: A7RIV with 200-600 +1.4 TC
Which one do you suggest and why?
Thanks in advance!
Always A7R when it comes to stills, it makes your lens collection double with apsc mode
I've just purchased a Sony A7R IV for £1500 brand new. I don't know too much about these cameras, but didn't want to overthink things, I haven't had a DSLR for over 10 years and am excited to be getting back into Photography. Yes, it's now a 3 year old camera, and there will always be better and better cameras, but for the price, and the kind of photography I will be doing (Landscape and maybe Street Photography) I am more than happy with my purchase. I will be buying a 16-35mm f2.8 and think that'll all be a nice set up. FYI, my previous DSLR was a Nikon D700 which I sold around 2013 (and which cost me £1700 brand new when I bought it in 2010 - so not bad price I paid for the A7r IV me thinks :) ).
Where did u get it at that price??

Yeah Apple is a bit slow with camera RAW support unfortunately.
fyi RAW file does support in IOS.
Updated with the current information and the RAW files are not supported in iOS
The most detailed comparison. Great video.
If i am using A7R2, should I upgrade to A7R4 rather than A74? I am enjoying with A7R2 42mp but its focusing performance lag behind recent mirrorless camera. Especial when shooting kids

you can pano but you can pano with r4 aswell to a greater strength
The ISO performance on both is so poor. Not only is the signal to noise ratio too high but the pattern itself is so offensive.
Great video I have both of these cameras and I love them.
Thank you, this was incredibly informative
Glad it was helpful!
A7IV has a Active Steadyshot mode which trade off 10% pixels for better stablization. It brings much better IBIS result. Looks like you missed it.
No, I talk about it in the video, but it never made a big difference in my tests. Using Catalyst is more interesting.
Cant wait for your a7r5 Test!
thanks a lot really, because i didnt know whether to get the r4 or a4a after watching your video , i decided to get the ar4
Glad I could help!

About 3m and a half for 1 minute footage, using the Mac Studio (M1 Max). Not sure how optimised Catalyst is for the M1 chip.
A fantastic analysis. Which of the 2 would you choose for underwater photography?
I have zero experience with underwater photography so I’m probably not the best person to give you an advice on this. I think they can both do well, considering the investment for a good housing and a good lens, perhaps it makes sense to get the A7 IV. But other people might be able to give you more information.
I'm thinking now that such good image resizing programs are available, there is no need for higher megapixels unless ones workflow is concentrated on super high res photography and videography
doesnt matter i am waitting for A7RV
my apologies you did briefly i m sorry . thanks for the information. i was undecided about which version to get , now i will just get the a7r4 thanks a lot
No worries!
sir i seen your video...please suggest which is better for weddings sony 7r v or 7r iv for both video and photos
Image quality is the same, whereas the A7R V has more to offer for video (10-bit internal recording, 8K, 4K 60p etc.). The autofocus of the mark V version is a step up, the EVF is larger with more resolution, so all in all I would say the A7R V if the better choice.
Thank you sir for your support
Which has better focusing ?
Thank you.. This helped me a lot in choosing !!
Great review!!!👌👌👌
Thank you! Cheers!
Great helpful comparison, thank you Mathieu
Will the A1 format print be very different between these two cameras?
Great comparison, thanks! Do you have any figure for the shutter life expectancy for the A7iv? I know the A7R series is rated for 500.000 shots but I can't find any info about the A7iv.
I don't think they released that information for the A7 IV.
What’s the difference between Sony A7RIV and A7RIVa?
As always a really informative review! Nice to see that you guys own films by the great filmdirectors of the past. I sometimes feel like a dying breed in these Netlflix ages...
Thanks! I studied cinema and film analysis after high school, truly fascinating.
@@MathieuGasquetMirrorLessons what camera did you record this video with?
Great video thank you
I have the A7riv & A74 LOVE My 2 babys
For you which is better?
Or best?
Edit: some grammar errors!
@@cjtubongbanua2367, it depends on your use case.
If you need high resolution work and need to crop in, A7R4 but buy it used on Ebay or aftermarket. You can get it about same price as new A74. I got mine for $2600.
If you’re a hybrid shooter and need both stills and videos, then A74.
I also have both of them and use them as the design was intended for.
I see a lot of users use it not for its strengths but for its weakness. Part of this to blame is Sony Marketing doesn’t do a good job to provide a buyer’s guide for their customers so they leave it to mostly user errors to determine the narrative.
For example, why would you buy the A7S3 for stills. But if you shoot only video, it’s A7S3 or FX3?
For sports or wildlife where subjects or animals are fast moving, you need the A1 (if you have the money) or the A9i/9ii, not the A7R4/4a.
Good luck!
Which one best for wildlife & bird photography??
A7 IV, mainly because of the better AF and Bird Eye detection.
@@MathieuGasquetMirrorLessons Thank u 🙏
I have the A7rivA and use it mostly for wildlife. Looking to switch to the A7IV asi like the articulated screen and it has better autofocus but I'm unsure if I'd miss the pixels.
You will miss the pixels.
With the A7R iv you have much more crop space.
I have both and use it for the same thing. Don't do it. The RIV wins hands down. The autofocus does not compensate enough for the pixel loss and dynamic range. Just my opinion.
@@247brownboot Agree. I bought it and returned it.
If you use a zoom lens like 200-600mm with a TC then the A7 IV is the winner since the AF will be superior. But ofc the RIV has more cropping capabilities. For prints, even 12MP photos can be printed on huuuge formats. So 33 is more than enough.
I feel like instead of only discussing MegaPixels in relation to image quality and printing we should also talk about the sensor and the end result regarding sharpness and overall quality. 33 is plenty. Cropping in is fantastic. But some cameras just take better images.
I had one of the first A7RIVs, I pre-ordered, that camera would never get focus. I just bought the A7IV, I am hoping this one is better.
Hi, could you do a comparison between the A7 IV and A7R V? I should like this
Will try!
Thx...what is the image stabilisation software ....as ibis is poor in Sony cameras for video
Sony Catalyst Browse, but it doesn’t work with the A7R model.
is there a green color cast on sony a7 r4 starting fro maround 3200 iso ?
Hmm not that I can see, it happens when you use the highest settings such as ISO 51200 or 102400.
I do landscape and some video. I wonder what model you would recommend?
A7 IV: the sensor is good enough for landscape, and the video capabilities are superior.
That was a great video sr
Thanks for watching!
I called the retail shop & booked Sony r7 IVa. Then did lots of TH-cam research, then cancelled it & finalised Sony A7 IV. Best decision :)
A7RIVA is built to a higher quality, but if video is a priority for you, it's understandable.
@@nubscrub A7 IV has better ergonomics, updated colors, faster af, faster storage, flip screen and better video. A7RIV has more pixels, but 99% of the people don't need that.
I did the same almost as you did. I received the 7R4 then viewed this video, then decided to return it untouched (I never opened the box) for exchange of A74 with a 80G CFA bundle, which will be arriving hopefully tomorrow. Cheers!
I own both. The A7RIV is better ONLY if you need the resolution. Oddly enough the A7RIV can shoot 10fps & the A7IV can't (that's unacceptable).
The insanely large files the A7RIV create are unusable unless you're a pro, you can't use them online without severe downgrades.
The A7IV is AMAZING in lowlight, the A7RIV is absolutely terrible.
Stop looking at 100% magnification looking for noise and you'll be fine. One camera cannot be amazing and the other absolutely terrible. That is complete nonsense, you are not comparing a FF and a m43 sensor...
Light Image Resizer. Compress the images, and you're done. I compress all images on my laptop. Quality is pretty much the same, file size is reduced by 80 to 95%, depending on how much I like the image =).
Hang on. The A7RIV is terrible in low light?
I own an A7r - expose correctly it’s perfectly fine up to 6400. View at 100 percent and you’ll see noise in any camera.
Thank you Mathieu for the excellent analysis.
A friend of mine is offering me the A7R lVa in a very low price and he didn´t use the camera.
Here in Argentina it is too expensive to buy one.
I´m a film maker not a photographer.
Questions:
1) Did you record with the A7R lV in 4K in a place where the temperature was 30ºC? You compare both cameras recording at 21ºC I remember.
2) If you use the A7R lV in 100fps ¿does the sensor crop the image? It is happens to me with my A7 Sll.
1) No, I only did the test at 21˚C.
2) I don't think it does but I don't have the camera with me anymore so cannot double check.
Have you encounter eye af focussing on the eye lash? Mine always focus on the eye lash not on the iris. Also the LCD freezes sometimes.
Is it possible that firmware update would fix this in the future?
Thanks
Are you talking about the A7 IV? Did you update the firmware?
@@MathieuGasquetMirrorLessons yes, already updated it but still the same 🤷♂️
That’s a shame.
I never had a problem with my copy of the A7 IV, even before the firmware update. I know about it because other people asked me about this, and also DPreview wrote about it. Not sure why some users are affected. Could it be related to certain lenses, perhaps?
New FW 1.1 fixes the problem, according to users.
15:20 like most TH-camrs you assume we can see a IQ difference at 100% but most of us watch this on a tiny 720p mobile phone screen. You need to zoom in 400%
Thanks :)
Please thank your wife from all of us! 🙂
38 mp for lossless RAW on a7iv is very seldom. Between 40 and 48 is normal.
I dont know what to buy. It cost the same here. No 1000$ difference.
Where is that? For the A7R IV brand new?
@@MathieuGasquetMirrorLessons its not what you thought :) Both cameras cost 3500$
Looks like Aberystwyth! :-)
Yes! I love that town 😊
Isn’t one a 61 mp
what about shutter lag. A7iii was a stinker for that, lab testing said it was good but in the field it was fantastic at snapshots of the past. Great for American politics
I have 2 a7r iii, smack in the middle lol
Youre making me regret my a7r iv purchase!
Cost the same in my country 😅
This video look just like the Sony a7 lV VS Sony a7lll
Спасибо больше❤️🇷🇺
A74 - very unsatisfactory flip-up display ...
What amazed me about your comparative review in reference to the Sony a7iv, there was NO mention of OVERHEATING when shooting video for an extended period of time. Many other reviewers & recent owners have complained about overheating issues of the Sony a7iv. Have you really tested this camera in real life shoots, or are u just going off printed specs from Sony? Please let us know.
You’re wrong. I DO mention overheating and also SHOW YOU the camera’s LCD with the recording time exceeding TWO HOURS. How about you REALLY watch the review, instead of questioning if I really tested the camera?
Had it been a Canon R6 (it's nearest direct competitor) it would have happened in 1/4 the time.
