Sony Announces the New Alpha 7R IV: A Proper Rival to Medium Format

For many photographers, having a high-resolution camera is a must. For some time now the Canon 5DSR was the highest resolution full-frame camera on the market. Sony has now one-upped it with their latest announcement the new Sony a7R IV. As someone who shoots with both Sony and Canon, I have to say I'm really excited about this new camera. 

Several times during the presentation Sony mentioned medium format and described how the a7R IV offers results rivaling such cameras. Personally, I think that's probably the case because considering the kind of lenses you can put in front of this new sensor you would probably be able to produce results that are better than some medium format cameras. Having a camera with 61mp is noticeably more than several notable medium format cameras currently in production.

There is also the fact that this camera can produce images with resolutions up to an astounding 240mp using its pixel shift technology. This is a ridiculous amount of detail coming from a full-frame camera and currently, it's beyond almost all medium format cameras except the Hasselblad H6D 400c; which is priced at almost $48,000. 

The Canon 5DSR was a brilliant camera and one that I regularly used, however this new camera from Sony really does rival medium format on a level which was not previously possible. 

Dynamic range is one of the aspects that medium format cameras tend to excel at and this is something Sony has seemingly worked really hard on. The a7R IV now boasts 15 stops of dynamic range which is extremely useful for a number of reasons. Recovering data is one thing but it's also the natural transitions between highlights and shadows that make images feel more detailed and lifelike. 

If this camera really does have 15 stops of dynamic range then coupled with the resolution it may produce images better than that coming from the Hasselblad X1D II and the Fujifilm GFX 50s. Although there is the GFX 100 which boasts a 100mp BSI sensor, the price of that significantly more than the Sony. For that extra money, you're not really getting a significant improvement in detail especially when you consider the pixel shift capabilities of this new Sony camera. Ultimately, the a7R IV is an incredible new release form Sony, one that may prevent the need to "upgrade" to medium format. This is especially the case when you consider the price and extra features this camera offers. 

Why This is Better Than Medium Format

Some of you will vehemently disagree with this and that's fine but I do believe this camera is a better option than many medium format cameras on the market today. First of all, consider the kind of lenses available for this camera. There is no equivalent for the FE135mm f/1.8 GM available for medium format cameras like the GFX or X1D. This lens is incredibly sharp too, possibly sharper than any similar medium format portrait lens. The fact that this camera also boasts more resolution than cameras like the GFX 50S and X1D also mean that you'll be able to produce sharper more detailed images with it. If it's just image quality you're looking for then more than likely this new Sony camera will offer better results than several medium format cameras that still cost more. Sure, you may want to bring up the GFX 100, which I do think is an excellent camera for a number of reasons. Although considering the price points, these two systems sit in very different market segments. Ultimately, the R IV might be the best camera you can buy when it comes to image quality up to a certain price point. 

Enhanced Autofocus

The autofocus features of the a7R III are fantastic and I've personally found them to be extremely reliable in many situations. For imagery, eye detect autofocus has been an incredible feature that has made shooting much easier for me. The R IV has improved on this by including real-time eye AF. This can be extremely useful for tracking moving subjects and prevents you from losing them when continuously shooting. This new sensor now has 567 focus points that cover 74% of the sensor. That wider coverage can really help with composition and may prevent the need to focus and recompose. This is especially useful if you're shooting with wider aperture lenses where the depth of field can be extremely thin. 

Better Video Features

During the presentation, there was no mention of frame rates and bit rates and for that reason, I'm assuming that they remain unchanged. What has improved are the AF features and video quality for super 35 crop mode. In crop mode the camera will downscale 6k footage down to 4k producing more detailed footage. The fact that the camera will not be pixel binning in crop mode could also help improve things like moire and low light performance. 

The autofocus improvements for video are very attractive. The R IV now offers eye detect tracking for video which is incredible.  Although the example shown in the presentation was of a very short clip, I think this could be one of the best features of this camera. 

The other improvement this camera has over previous models is touch to track focus. on the a7R III when you touch to focus on the back screen, you couldn't actually track your subject. This is something I've requested multiple times and I'm really happy this has now been included. For video shooters, this could be extremely useful, especially for those of us that film using gimbals.

Other Improvements

Sony has really improved the build and design of this new camera too. It looks as though this new camera might be a little thicker than the previous model which I think is definitely a positive point. Having a slightly larger body can help prevent overheating which is something that plagued older models like the Sony a7R II. The R IV also weighs slightly more than than the previous model the a7R III but by a negligible amount. The grip was also discussed as being improved based on what many photographers requested. I too felt that the grips on previous models were a little uncomfortable so this is a great new improvement.

The R IV also now offers two UHS II card slots which may prevent the bottleneck that the R III had. On the previous model due to the second card slot being limited to UHS I, anytime you were shooting with two cards, the camera would slow down or entirely stop when writing data. Thankfully this may not be a problem now. 

The higher resolution viewfinder is a very welcome addition. That extra resolution really does make a difference and having shot with several cameras with high-resolution viewfinders I have to say it's extremely useful. It not only helps you to see what you're photographing more effectively but also you can preview your images properly. 

Better Color?

One of the biggest criticisms that Sony has had is how it renders color. This has been especially true for skin tones and in some tests and comparisons that I've done, I found Canon to be definitively better. It would seem the R IV might be better when it comes to color and skin tones. This is mostly speculative right now as no side by side comparisons have been done, however, the skin tones in the image above look pretty good. Those strange green-ish tones aren't visible and this is making for a much nicer looking image. I personally found Sony to have trouble with darker skin tones, yet the R IV seems to be doing a pretty good job in the picture above. Of course, some proper testing is required before any actual conclusions can be drawn. 

Expected Features That Are Missing

Based on the rumors that were going around prior to the announcement many people were thinking that Sony was going to release a camera with the ability to shoot 8k video. Of course, this is not the case and honestly, I'm not disappointed about it at all. What I am a little, tiny bit disappointed with is the fact that video features remain mostly untouched. The camera still shoots 4k 30p and only 8-bit 4:2:0. Personally, I think 4k 60p even if only in crop mode would have been brilliant. A full HDMI slot would have been beneficial for many video shooters too. Having said that I'm aware that this camera is more for photographers and Sony has always differentiated the R series and S series of cameras. Even still, I think that giving the ability to record at higher bit rates via an external recorder could have been sufficient. 

Final Thoughts

Sony is really pushing for that number one position in the photography industry. New cameras are a regular thing for them as a company and they're making it rather difficult for others to compete. I think this new camera is a brilliant addition. Sure, I'm ever so slightly disappointed about the lack of improvements when it comes to video frame rates and quality, however, this is a photography specific camera first. This also could mean that Sony is saving all of its high-end video features for the potentially upcoming Sony a7S III. Ultimately, it's a great time to be a photographer because cameras like these are making our jobs much easier. I can't wait to see how this camera performs in real world situations. 

The Sony a7R IV will be shipping in September this year for $3500, preorder yours here.

Good thing it's unrivaled as a photo camera.

"I’m gonna wait to see what canon does...." is basically what Canon fanboys have been saying for months now. They've been saying that before the EOS R was released and have still been saying it even after it was released. I'm pretty sure people would still be saying they'll be waiting what canon does even after their next release.

Well let's just wait and see what Canon does.

Correction: The Canon fanboys have been waiting for years for Canon to catch up. So far, Canon have failed rather miserably.

Weren’t you the guy who said he had to buy a new sony because yours broke down for a second time?

Keith Meinhold's picture

I switched from Canon to Sony seven years ago - because the offered nothing that would compete with Sony's NEX (mirrorless) system at the time. To my mind they still have not come close. If the tables turn and Canon offers a small light camera that outperforms Sony's offering - i wouldn't hesitate to switch back. Does not look like it will be anytime soon though.

"basically what Canon fanboys have been saying for months now"

Months? I remember that from back in the 5D III days. Then people were horribly disappointed by it when it came out. Not much has changed since then.

People who vote someone down because they provided reasons why they personally wouldn't buy a camera are people not worth knowing.

Great camera but.... i wait for the canon pro. I think this will be a better one...

Better to be put into a medically induced coma than to wait it out being conscious.

Jan Kruize's picture

I know... i compared my pictures on this website with yours... and yes... i should be ashamed.

You keep metioning the photos you have uploaded here as if you think people give a shit. Its almost as if you think they're more than just than technically competent...

Jan Kruize's picture

yes i know. people don't give a shit about photo's in here. I'ts only blablabla about gear. What people do with it? Who cares...... very poor reaction man.

Jan Kruize's picture

No they don’t, but i don’t understand what someone is doing with a 3300dollar camera, talking like they invented photography and showing nothing.

Jan Kruize's picture

Be honest man. When a company brings out in less than 5 years 3 models A7RII, A7RIII and the A7RIV. And when the A7 RIII came on the market They proudly say yes you can make more than 250 photo's on one battery now and we added a joystick, and with the A7RIV yes we made the camera more dustproof as a professional photographer.... do you really take this serously? The only thing they do is getting as much money out peoples pockets as possible. Pushed by a lot of sponsored influencers Sony is not more than a brand for amateurs at the moment. Really, the image quality is good, but the rest?

Good luck waiting. You have been waiting for years now. Another couple of years waiting won't make a difference. I now seriously doubt that Canon has the sensor technology to be better than Sony.

Jan Kruize's picture

Yes i know.... it’s miserable. I didn’t do anything for the past years. Sony should be ashamed that in less than two years they bring out a new one. They fucked up all the people who bought one two years ago. And then saying proud eww yeah we made our dust and moisture protection better. They really only want your money and for the rest they don’t give a shit.

Yeah, Sony fucked up for bringing more innovation to the market than any other camera company. Canon just announced their new mirrorless cameras will have IBIS! What innovation there. People who have the a7riii aren't obligated to sell it. But yeah man options are the worst huh? Only if Canon had options. Keep mentioning that you have photos on this website, people really love them and their grabbing a lot of attention by themselves.

Jan Kruize's picture

Oooh yesssss all this glorious sony innovations.... did they tell you when you try the auto-af on your donkey it doesn;t work? Sony just brought out camera number god knows what to pick money out of your pocket. Just show what you do with that bloody thing man.

You should change your name. It should be: The Angry Photographer II

Jan Kruize's picture

Ohhh yeahhhhh.... thats better than mr bigboy sony Jason Lanier.... oh wait... the guy is working with a canon eos-r now... and he has some issues.... man... goaway.

Do you proofread your text?

Yeah, the camera won that award.. Not the photographer. Nice one.

Jan Kruize's picture

No Sony.... you see? No Sony.... why? Theyre a lil weak. No one of this winners use a Sony. Why? They’re professionals. And all these influencers try to let you believe they have award winning camera’s. There are no Sony’s in the big professional field Only Nikons and Canons. In the amateur market Sony is becoming bigger and bigger. Not in the proff. field.

A lot of people are still making the switch because they realize how capable Sony cameras are. For instance, in the world of sports, many professionals use the A9. Just wait for the Olympics to come around and you'll see a lot more of them. I've seen a lot in congressional hearings as well. Sony's way more capable than any other camera company on the market. You're a stubborn and angry one aren't ya?

Jan Kruize's picture

Wrong mate...... there isnt any sony in the professional field. At the dutch-TT there were only Nikons and canons. And one Sony. Was a Spanish photographer sponsored by sony. Sorry but i can't help it.

David Love's picture

Well let's just wait and see what Canon does.

I'm sorry, my English is not as good as your dutch...
