Sony A7 IV vs A7R III / A7R IIIa - Which One is Better? - Full Comparison!

Very informative video Thank you. Please tell A7 iv have High-speed steel (hss) or not....

Thank you.

I don't think I will change from a7riii to a7iv since I am only capture landscape, cityscape and non fast moving subject. 42mp is big win for me.

I just bought a Sony a7RiiiA. I understand they've made a few improvements. I don't shoot a lot of video. I can't remember the last time I did. I had a Sony a7iii which I sold recently and have been shooting with a Sony a7c. The a7c is a small camera that's great for travel but Sony has discontinued it and it is two years old. I'll keep it for travelling around town and as a backup. I should have the new one before I travel to the Baltics, Sweden, Finland, Poland and Germany.

Thank you for making this comparison! Sub’d!

I already own a A7iv, which is normally fitted with my Sony 200 - 600. I wanted to upgrade my second camera, an A7Rii, which I use mainly for landscapses and macro, really just for the joystick and the battery type.

I wanted to part exchange the A7Rii, along with a Tamron 28 - 70 RXD version and an Olympus lens I no longer use. The A7iv is still £2400 in the UK, but at London Camera Exchange they currently (Mar 23) have a special offer of £1500 for the A7Riii, so it is a no brainer and as a bonus, the part exchange is going to easily going to leave me with enough to purchase a new pair of binoculars, as well as the camera. Roll on Friday.

You’re so helpful ❤love from Bangladesh

Which is one is better A7 Riii or A7 RiiiA??

I sold my a7RIII for the a7IV. Better all rounder, bird eye af is a game changer for me as well as full auto focus tracking with 200-600 + 1.4tc

I heard that updating a7riii firmware to 3.0 gives you eye af in video; is this true?

Best camera for faimly photography in 2023..amazing sharpnes excilent lowlight photos..best dyminc range
..plzzzz guide me. Which camera body or lense best for me..photos or video?

Thanks you, very informative especially for what I was looking for 👍

As a land- and cityscape tog with tripod and manual focus I see zero reasons to dig my RIII. Thanks, good work.

this must be one of the best no bs camera reviews i've seen lately. thnx.

i'm currently deciding between 73 and r3 as i'm seeing very low and comparable prices on the used market ($1000-1200). the autofocusing looks a bit slower but obviously the r is a higher-tier model and makes more sense especially when at the same price, despite being a few months older with a few upgrades left out for the 73.

i am concerned about the weaker iso performance, due to the higher mp count seen mildly in the 74's mp increase. from what i've seen so far the iso difference doesn't seem significant. is the iso difference notable or tolerable?

i'm also concerned about moiré issues in the r3 due to lack of a low-pass (a-a) filter although it seems like the aliasing could be avoided and potentially taken care of when necessary. the 74 also seems to have dropped the anti-aliasing filter, i'm reading that it's not used for cameras with higher than the standard 24mp, as aliasing is more prominently introduced when the projected lens resolution is higher than that of the sensor. doesn't this mean the 74 is even more prone to aliasing than the r3? would the moiré on the r3 be an issue for general model, product and architectural shooting?

thanks!

Спасибо! Отличная работа!

Good comparison. If you are shooting RAW stills, manually focsing, profiling the camera and manually white balancing the improved picture profiles on the IV become meaningless and the RIII still wins on image quality; delivering a 80+ megabyte file with more information than the 60+ megabyte file from the IV. Depending on viewing sizes this is quite significant. And even more significant if using the multishot function on the RIII. For video, general travel use and environmental portraits I would get the IV and for action the A9 or A1.

Hope Sony just rease an updated 40mp+ camera with lastest AF...still using my 7yr old A7r2

danke für dies ausführliches Video👍

You need to get more love in this channel. So much work, effort and time is put into each video... Hope you can keep the workflow consistent and push forward. Hope to be able to make quality content like you in the future!

I have the A7RIVA and bought the A7IV. Was very disappointed in it to be honest.

very throughout review

Here I am trying to decide if I really need to wait for the A7R V or if a used A7R III or A7R IV could be good enough, finding out that A7 IV might be even better? I currently own an A7 III and pretty much only doing stills.

Hey Matthieu, great video once again. I saw your A7R4 video as well, and I have a question.

When the A7R4 is connected to a field monitor in VIDEO mode it loses autofocus function like face detection. (Many have spoken about this and given solutions ie Gerald Undone)

However, video is NOT my concern.

For still photography. Do you know if the A7R4 loses any autofocus functions while connected via Hdmi to a field monitor?

Excellent video. I'm looking to go FF from APS-C and these are on my radar. Is there a reason why you did not compare the A7IV to the A7RIV instead of the RIII? Would that not have been a better comparison or is there a meaningful reason that I am not aware of?

great review dude waiting for more

Thank you for the video comparisons you do, Mathieu. This one in particular was great timing for me. On the fence between these two models, but your insights helped. -Carole

Nice detailed comparison...

Today at July 16. 2022 the Sony A7IV are $2500 and the Sony A7RIIIA are $2200, so it is a VERY easy choice for still Photographers, the Sony A7RIIIA are both cheaper and have more megapixels ! I had the Sony A7RIII which are a great Camera, now I have Sony A7RIV and A7RIVA which right now are only $3000 !!! So the best buys are either the Sony A7RIIA or the Sony A7RIVA for still Photographers ! Be aware that a new Sony A7RV will arrive in the autumn !

Best side by side review on the net as always.

It sucks that a7iv front focuses on eyelashes wide open. I'm gonna wait until Sony fix this problem before making a purchase.

very informative comparison. As an A7RIII owner, I feel so excited about the differences between the two. Could not imagine what my next camera is gonna be like after I retired my A7RIII in 2027.

Great Review Mathieu!!! I would even say the best review in direct comparison!
Fun Fact - i sell the A7R IV to sidegrade to A7 IV because i´m not happy with the iso perfomance.
Last Month i bought the A7R IIIA, because i only use (35mm & 85mm GM)...
Thanks a lot for you´re great work!

Well that's sucks with the A7iv you get amazing AF but then get kicked in the balls with the burst rates...

Also, on the a7riiiA they moved to a USB-C port instead of the mini-HDMI (Also, the a7riiiA firmware is 1.01 too)

Thanks for posting this series of videos. The A7IV ticks so many boxes. I wish they could have gotten the lossless frame rate a bit higher (I take a lot of wildlife photos), but other than that it seems like a perfect camera. It's interesting how Sony's colors have meandered from green to red and back to green over the years. I'm currently shooting Panasonic GH5 and Nikon D500 and it would be nice to only have to carry one body with me in the field. I'm guessing the A7R3 autofocus is outclassed by the D500? I rented the a74 with 200-600mm and it was very competent! I did not miss the d500 at all.

Love the channel. For me this is pretty much a no-brainer. The A7IV is the clear winner here, unless you do primarily still subjects. That 42meg sensor is great and add the pixel shift function really works well (again for still subjects). But if I had an A7R III, not sure I'd sell it for an A7IV.
