Glad it was helpful!

Thank you! Much appreciated!

My pleasure!

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.

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.

Can I see your photos of birds with a7IV?

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.

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.

@@MathieuGasquetMirrorLessons Thanks.

you can pano but you can pano with r4 aswell to a greater strength

Thank you! Cheers!

I don't think they released that information for the A7 IV.

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

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.

@@MathieuGasquetMirrorLessons thank you your opinion means a lot to me. I've always trusted your honest reviews and insights

Sony Catalyst Browse, but it doesn’t work with the A7R model.

No worries!

Glad I could help!

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.

Thanks! I studied cinema and film analysis after high school, truly fascinating.

@@MathieuGasquetMirrorLessons what camera did you record this video with?

The A7 IV has the better autofocus, and 33MP is plenty of resolution already, so I would go with that model.

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.

No, I talk about it in the video, but it never made a big difference in my tests. Using Catalyst is more interesting.

Thank you!

What did you buy at the end?

Sony added different sizes for the RAW file to the A1. Perhaps they could do it for the A7R IV as well.

@@MathieuGasquetMirrorLessons 6500$ later, they could have added some lenses :-)

Thanks for watching!

I'd say the A74 is the better choice concerning the autofocus.

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.

A7 IV: the sensor is good enough for landscape, and the video capabilities are superior.

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.

A7 IV: it has more to offer like 4K 60p, 10-bit video, etc

Will try!

Hmm not that I can see, it happens when you use the highest settings such as ISO 51200 or 102400.

Where did u get it at that price??

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

A7 IV, mainly because of the better AF and Bird Eye detection.

@@MathieuGasquetMirrorLessons Thank u 🙏

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.

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.

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!

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

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!

Yes! I love that town 😊

Where is that? For the A7R IV brand new?

@@MathieuGasquetMirrorLessons its not what you thought :) Both cameras cost 3500$

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.

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.
