Of all the camera reviews here in KZfaq, this one is probably among the top 5 in terms of quality, presentation style and overall impression. Pure excellence.

I can't stop staring at that 85mm GM glass. It's so big and clean, it's like looking into the cameras soul

Mark, your videos are really comprehensive and detailed without the drama and heavy bias that so many others do. I really enjoy and appreciate your work!! Thank you!

Thank you Mark for all you do supporting Sony. When I got my A7Riii back in 2017 your videos were a constant guide for me learning a whole new system. I page by paged copied your settings. I just got my A7R4 & uploaded your settings. Made the camera feel like home to me.

Thank you Mark. This is by far the most useful "early" review of the Sony A7R iv that I've viewed on youtube to date.

Another great video, full of info without the fudge, and I love your work. Thanks for sharing.

Mark, thank's again for your really good review! 👍 I am so happy to find you on KZfaq and you are the best expert for me and I love to watch and learn from all your content. Sony has with you the best Ambassador for sure! Many greetings from Germany and I can't wait for your next content! 👍

Exceptionally balanced review Mark. You provide the most comprehensive and pragmatic perspective on gear. It’s greatly appreciated.

Just super, thanks Mark. I am first in line with my pre-order at my dealer for this A7RIV. Can't wait, I have plenty of G-Master and other top glass to use with it.

A lot of this went over my head but that's what I love about photography, always something new. Thank you for your time Mark. I have the a6000, a6300 and a6500. I'm ready to make the full frame bump and will be purchasing this camera in September!

Finally a complete video about the A7R4 camera. Well done

Nobody can touch Galer's quality and content -- amazing review. You've sold me on an upgrade to the A7RIV.

GREAT Video Mark the best and most detailed A7RIV video!

Always love your reviews, thanks for the share, I may get this for shooting standing birds and crop in in post to extend my 400mm lens in stead of getting the 600mm as you suggested, cheers!

You do make life easy for those of us who have had no formal traing in photography but have picked things up as we have progressed. I'm also older and not given to the tech side too much. Thank you so much for this review.

Love sony Cameras, and having been using them for the last few years, this is my go to channel when i want to know about my camera, and its uses, brilliant channel !!

Always great info Mark thanks 100%

This is a great review of this camera ! Well done.

Thanks for your informative review. Nice to see people who aren't biased or completely hell bent on shooting down the newer cameras.

Another fantastic video... My A7Riv arrives next week and now I know what to expect. Thanks, Mark!

amazing review, thanks ! I've already pre-ordered it and I'll get it on the 26th of August!

Always love your instructional videos :)

Fantastic as usual! This is why I switched it up to Sony a few years ago. Even as competition starts to catch up they continue to improve and press the envelope. I probably will not get this camera but am really looking forward to the same new features that will come in future Sony camera releases!

I appreciate that you tell us facts quickly I subscribed

Fantastic review Mark and really appreciate your very comprehensive review

Thank you so much for this video! Solid as a rock.

Amazing video overview as always Mark. Glad to see you are tryng to squash the haters/complainers crying that this camera was not the A7S3 :) great updates by Sony. They keep pushing the limists and are light years ahead of Canon/Nikon. Cant wait to see some of these features trickel down to the A7IV line which is what I am saving up for when it comes out as I dont really need 42 or 61 MP :) Keep up the great work you do Mark.

Thank you so much for this video. I can say that in my opinion, you are the best regarding Sony videos ! Bravo Monsieur !

What I absolutely love about this camera is the crop mode with 26mpx When you combine your 24mm 1.4 equals 36mm in crop, and a 85mm 1.4 equals 127mm crop mode or the 135 1.8 equals 202mm this is by far my most lover feature. Instantly a bigger buffer and more space on your memorycard/ hardrives. And at the same time I don’t need my big and heavy zooms like the 24-70 and 70-200gm. The primes are faster and let in more light! And when you want that extra resolution, you have it!

Hi Mark, Thanks for an excellent comprehensive review. I'm new to your videos, had been deterred by length (and thus time needed to assimilate) but realise now, having appreciated the detail and depth you cover, that your vids might be worth making time to view vs. many 'thin' vids on other channels. Would love to buy this camera and will probably do so one day. Currently have the a7R3 which I really like. I'm not convinced I need even bigger files for most things I shoot (just amateur use for own gratification) but aside from bigger file size the many other upgrades do seem like a useful gain. If it had the ability to downscale to say 30 Mb RAW files whilst retaining full frame then that would have been perfect for me as less pressure on buffer in sports shooting and file storage when you know you don't need higher res. Other downside is I might need to use GM glass? I have the 24mm f1.4 GM and 55mm f1.8 which are lovely but I also tried to save weight (for travel) using the f4 (rather than GM) versions of 16-35mm and 70-200mm. I wonder ifI would also need to upgrade these for extra cost and weight in order to really see the benefit of extra pixels and resolution? Anyway much to consider. Might look at trading in my a7R3 for new a7R4 but won't do anything until I know where a9 (on price) goes and a92 goes in terms of features, resolution and price - because if it had all upsides of new a7R4 (apart from res) with a circa 30Mb res, with faster buffer, better focus aquisition etc, then I might be tempted with a pairing of a7R3 (retained) + either a9 or a92 for when I need fast sport. Whatever ..... as dilemmas go, it's nice to have choices.

Excellent review👌 thank you

great rewieuw, thank you Msrk.

My go to pro for learning my new sony system. Thanks mate.

I am looking forward to the 1:1 crop format. I prefer a square crop on many subjects. It will provide a 40mb file, using the sweet area in the center of the lenses, and can be cropped 3:2, horizontal or vertical and still yield a 26mb file.

Hi Mark - just a random comment wishing you a great day. You’re one of the very best!

Great review

Hey Mark, great video! I’m curious, is there a 4:3 aspect ratio in video? Would be great for anamorphic lenses. Also, could you make a suggestion of 4:5 as an aspect ratio choice for stills next time the engineers ask for input. Thank you sir

Thank you Mark this is amazing video 🙏

Thanks for feed back.

Great review. Long time Canon user. Love my 5DMiii it thinking a lot about mirrorless lately. Will be ordering ARIv now. Tvm for a great overview.

Thank you for a detailed and insightful review of the A7R IV, Mark! I am really looking forward to mine. You have covered a lot of nuances that most other reviewers haven't even thought about! The only thing the A7R IV is missing is a high res multi-shot mode as in the Panasonic S1R. I suspect Sony got flat-footed by this surprise feature in the Panasonic S1R, and did not have the time to put in this feature. I suspect this feature will need custom Silicon, so we may not see it until the A7R V some 2-3 years from now. (The Sony pixel-shifting doesn't even begin to compare).

Thank you for a perfect review. I have just sold my Leica Q2 to upgrade to the A7R4 from the A7111. During lockdown I became really interested in bird and other wildlife photography, (it was local!). I bought the 200 to 600 lens, but was finding that I still needed to crop, particularly with the smaller birds. I am hoping that the extra pixels will still leave me with a reasonable file size. I also found with the A7111, that I had a lot of noise in the bokeh when I cranked up the iso to maintain a high shutter speed. So am awaiting delivery with anticipation. I think your site is such a fantastic training and education tool.

Thank you for providing originals to download, I can't wait to put them on a thumb drive and display them on my 85" 8K tv!

You just convinced me to buy this camera!!

Thanks for the honest review. I cancelled my pre-order (based on the tracking being less the A9) and will await a possible A9 variant purchase.

Love the channel Mark. Quick question; does the crop mode affect the depth of field as well as the perceived focal distance?

Great review. I have to laugh when anyone says " who needs that much resolution " it's like saying " who needs a DSLR when you have a phone camera " 😁

Impressive review! So comprehensive and complete. Thanks! By the way, the 135 GM glass impressed me. Seeing the blades through it was just spectacular. How does it compare to the 85 GM?

A7R IV + 135mm GM is a monster combination for motorsport. Vehicles are not birds, their paths are predictable. You do not need A9. Meanwhile the resolution and image quality from the above setup beats everything.

Great overview, Mark! I'm glad I'm not the only one waiting for what the a9ii is gonna be. If it has a slightly higher MP count, this new grip, and picture profiles I'll be there day one.

great review Mark as always.. i wont be getting it . least right off.. i perfectly fine with teh a9 and a7riii and a7iii... but once a9ii comes out i will get it. and maybe when a7riv is bundled with some deals next year i might. but do like some of the features they added.

Good detailed review. BTW, I have found that increasing the picture profiles to +5 helps considerably with manual focus lenses - as long as you're shooting RAW.

What a great review Mark. Thank you for all your effort. I was thinking of switching to Sony for my first full framed camera and Sony here I come. Anyone out there wants an 80D? LOL.

Thanks for this review and commentary, Mark.

Super predstavitev!Bravo!

Thank you, Mark, for basically getting to the meat of the matter for those of us making the upgrade from III to IV.

Really solid job on your videos...always deliver good information without the histrionics so often associated with new gear reviews. Do have a question - my work is approximately 40% landscape/40% wildlife (mainly birds) and 20% flowers. I currently shoot an a7RIII. Is the approved autofocus of the a7RIV for wildlife worth the upgrade? I don't want to purchase an additional camera because I've pre-ordered the new 200-600mm sony lens. Appreciate any thoughts. Thanks.

Another marvellous introduction video Can you do one on the RX1007 please Is the other end. I run mtbike and tramp. I find my A7III is a bit big and I can wrap the RX up just for when I fall over run or bike it doesn’t get broken Would really appreciate Cheers

Thank You that was a thorough video! I love it! The only think concerns me is when you say for BIF I might want to get the A9. Is there that much AF difference? The pixel density difference I would have thought would more than compensate for a little faster tracking on the A9 a lot more of the images would be crop-able and still look great.

Dear, sir! A very big THANK to you for an amazingly interesting and highly informative review you have generously given us on your excellent channel! (Thumbs up and also subscribing to your channel!) Wishing you all the Best! Greetings from Sweden!

Great review Mark. As someone else posted, your reviews are the best. Thanks .

love it!!! join in guys!!

I would expect Sony *could* release a firmware update to include a small size (and medium size) option for .RAW images for the A7RIV fairly readily if it had a mind to. Hopefully consumer demand will prompt this. I enjoy my A7RIII but the additional features of the A7RIV can't be denied. 61 MP will be a pleasure to use, but will require GM lenses for best results, so there's that to consider. The improved resolution of the EVF, deeper grip, larger buttons, improved weather sealing, and the exposure compensation lock button are all things I'd really appreciate. It looks like Sony will have a real winner with this camera. My only significant complaint, of course, is the lack of a fully functioning touch screen. It's not a "deal breaker" considering all the great features of the A7RIV, but to release this level of camera, without that feature, is both perplexing and irritating. Regarding astrophotography, I suspect the A7RIV will still suffer from it's previous "star eating" issues. I extensively tested my A7RIII, with the latest firmware update, against my Nikon D850 and despite some websites claims, the A7RIII, in side by side comparisons, does fail to resolve stars that the D850 has no problem with. Great images and the detail from this camera with GM lenses is simply stunning. Thanks Mark.

Your full-resolution shot of the pier is just incredible. I can hardly wait to see/take shots with the a7rIV + 24mm f/1.4 GM combo, not to mention the 400mm and 600mm lenses.

Excellent!

Hey Mark. Again best information about the camera I have seen. Just ordered the camera and looking forward to your ebook. Thanks

Very solid review Mark, Love it.. So now i want sony to release a 100400GMV2 i guess, still not sure about this or waiting for the a9M2 with 36MP or 42MP.. sigh... some nice new features.

Hi Mark brilliant video Thanks. Quick question I looked at the photos on flicker and I am sure you must have used burst mode when photographing the dogs. Did you experience any black out as I have just seen a comment posted by someone that the black out was terrible?

An excellent overview, thanks Mark. I have been toying with this camera for wildlife as well as the D850. Accepting that you are a Sony ambassador, what are the advantages of the Riv over the D850 and would you recommend it for wildlife? Thanks, David

Thank you Mark! Excellent as usual. I've decided that when I upgrade from my A7III I will likely go with an "R" series camera, likely one of the currently available "R" camera either this R7IV or even the A7RIII. I will pass on the A7IV which seems to me to put too much emphasis on video, which I seldom use. Is the A7RIV still relevant? I wonder if we can expect the next gen to have the same videocentric emphasis as the A7IV? I would like the ability to print larger and prefer the tilting screen of my A7III over the flip screen. You remember the A99's articulating screen? that would be what I would like to see.

I had Sony a7R IV with 35 1.4 and 100-400 and it was such an amazing combo that I will never get over it for selling 😭

Remarkable. Thanks.

Thanks for great video content. I was particularly searching for feed back on battery life. I hurd improvements have been huge so it might be obsolete to ask, but I'm looking at upgrading my 7rii so I still have that in mind. Just to be sure, can you please tell us how this one perform next to the latest relised 7iii?

You're amazing Mark; thank you.

Nice review Mark, thank you. This may be a replacemnet for my A7III in 12 months time, depending on whether Sony relesaes something more appealing to me. I will not be replacing my A9 anytime soon as it is just so good. I've just replaced my 100 - 400 G Master + SEL20TC with a 200 - 600mm + SEL14TC, so I hope the A7RIV works well with my new lens.

Awesome Mark. Can you tell me what is that LAV mic you're using?

This might be the camera that finally makes me makes the jump to Sony, I didn't really need 60 megapixels 50 or so would have done fine, but I do want better ergonomics and weather sealing. The Sony lenses have now improved to the point now to the point they are class leading, although probably a touch too expensive.

Thank you very much for your video. And can you please make a video to compare the photo quality of Sony a7r3 and a7r4, using the same lence and shooting on same objects? Because a7r4 has more but smaller pixels.

Thank you for your review Mark! As I make some astrophotography with my A7R III, I'm curious how the Mark IV handles high ISOs and the noise especially at such high resolution. Do you have some information about this?

Any thoughts on whether the 16-35 f4 FE lens can take full advantage of this sensor? I'm trying to decide whether to sell it and save for the GM version. Thanks for a great review. Your reviews are much better than those of any of the other Sony artisans.

Dear Mark, I love your reviews, very clear and neutral. Maybe you can give an advice. What do you think about the F 18-135mm in crop at the Sony A7R IV? It would keep the camera fairly light for travelling?

Hi Mark, excellent vid. One query.... did you notice anything re a high propensity to attract sensor dust (hypothetically a static issue?). Tony Northrup seemed to think that this new model appeared overly sensitive to that issue vs. other models - he otherwise loved camera. Would appreciate your perspective on this point. Thanks

I could not take my eyes off that lens!!! ;-))

I have the A7R II. And Used Metabones and Sigma adaptors for Cannon 11-24 lens... Very Hit or miss.. I suppose I could have gone for the sony 12-24 when it arrived, but I didn’t. Had to Connect and remove frequently before autofocus worked But the lens worked straight away on A7R iv, And the focus is fast now... I know its not something that gets mentioned now that Sony has loads of lenses, But I was impressed with how FAST the adaptors now work..

I'm just sitting here staring into that beautiful glass on what I'm guessing is the 135

the sensor or the r4 is a very slight smaller than the r3. What difference does it make?

Great review, but how does the crop mode performance compare to using a crop sensor camera?

Wow, really phenomenal review. I will be getting a new camera. Just need to know about the details of the a92 first. Thank you.

This is the video that finally convinced me to support you financially, Mark. I simply went to MarkGaler.com and donated USD 60 via PayPal, which is the equivalent of a $5 monthly Patreon subscription and which I strongly suggest to everyone else who has found your videos useful. Mark, I find the need to be explicit here, because you are so modest in promoting yourself, and I want you to keep up your great work! You are so very balanced and careful in your reviews that I detect no intrusion of commercial interest into your educational mission, even though I know you are a Sony ambassador. Mark, I have also downloaded your e-book on the a7rIV-which I also find to be very useful, especially those pages that detail your custom settings - and I have added it to my Apple Books library. This e-book is ten times more useful than the “presets” that others sell to support their own work-no disrespect to those people, but I simply find your custom key settings, your function menu settings and your other custom a7rIV settings more useful to me. I wish you would also make your make your “backup” file available to us, so we could see everything you find useful! Finally let me simply say thank you, Mark. I return again and again to your videos, as I find them more helpful to my business and personal work than anyone else on KZfaq. Just today, I was experimenting with AF settings on my new a7RIV and once again found you were spot on in your advice about photographing wading birds in flight. This one piece of advice alone was worth the $60 I just sent you! Thanks again, Mark, and do have a pleasant weekend, Arthur

Sweet camera. 2 thoughts: (1) A lot of these functional improvements seem to be inspired by Panasonic, since they've been implemented by Panasonic since the GH4. (2) Panasonic probably better drop the price of that S1r down to $3200 to gain some users before this thing launches and eats their lunch...

Hi Mark. Thank you. Most of the comparisons of the 7Riv have logically been with the 7Riii. However, I'm curious about comparing to the 7iii. Especially interested in the auto focus, viewfinder and high ISO comparisons. Thanks again.

The images from the 135gm are incredibly sharp, and those from the 100-400gm are amazing as well.

Mark, Thanks for the review. I was wondering if the sensor readout is any faster than that of my A7R 3. In silent shooting, I get banding at higher shutter speeds and unfortunately negates the usefulness of this mode. It is really useful for concerts, and events where extraneous sounds are distracting to the event itself. Is rolling shutter better in the Mark IV vs Mark III? I am happy that real time tracking has arrived in the R series, and it will enable better AF accuracy. Using APSC mode to extend reach seems to be a waste of the capabilities of the IV. Would’t using an A6400 instead make more sense? I think the upgrade should also have included faster sensor readout via a stacked type design to help move the massive files generated by the 61 MP resolution. After all Sony already has had the technology for a couple of years.

I did watch on 4k oled and it's nicely crisp. I would like to have seen more on low light performance, 1:1 and such. And compared with A7 III. I figure if you lead with resolution (+dyn range) and low light you cover the sensor tech right away. I get the impression that it's not better tech than mark III for light sensitivity.

Good day Mark, please I don't understand when you say that Capture One doesn't support the 'Raw File' format for the Sony α7RIV.

Already with the A7 R II I thought that this camera was calling for the best glass; so I decided to have primes only: 55mm 1.8 and 85mm 1.4; with the A7 R III I decided not to upgrade to a new generation, as I had some doubts that the quality jump would be medium only; the came the latest firmware of the autofocus and an upgrade became justifiable; I started saving; now as I have the money, I will get the A7 R IV. Fortunately I have the right lenses; So we should say it clearly: the higher the resolution f the body, the higher the resolution of the glass: GO PRIME

Hi Mark, I subscribed to your channel. Where exactly do I see your monthly webinars or other content available only to subscribers? Is it on KZfaq or from your site? TIA...

Thanks very much for the video! I'm considering upgrading to A7Riv, but not sure if my non-GM lens (28/2, 35/2.8, 55/1.8, 85/1.8）are out-resolved by the sensor. What do you think?

Thank you for this review. I have an R3 and when shooting silently, I have banding. Has this been completely solved now?
