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.

I don't think that I ever implied that your being a condescending asshole had any bearing on the validity of your arguments. The only thing I said in regards to that are that you are one and I enjoy conversing with them. As for you being right or wrong, like I said, I'm not even sure what you're trying to argue as your initial comments were just some bullshit ramblings about the "the marketing machine" and the obvious fact that marketing employs psychology in an attempt to get you to buy things (something that we were taught in grade school).

Will Murray's picture

Yes; I've spent more time in university than I care to admit.

"...they are all idiots..." does not a thesis statement make.

michaeljin's picture

That makes two of us and I didn't realize that we were in an academic setting. Last time I checked, this was just a casual exchange on the internet.

Will Murray's picture

Your assertion is that everyone who engages in such behaviour suffers from mental retardation...

And you wonder why I conclude you are wilfully ignorant.

michaeljin's picture

Oh please, you know exactly what I mean...

Will Murray's picture

I know what you said. Your subjective intention is in your head.

michaeljin's picture

For someone who seems to complain about others not being able to read the subtext of his statements, you display a remarkable deficiency in that regard.

Will Murray's picture

There's no significant subtext re my OP. Granted there is a significant body of accademic work underpinning what I said.

The word "idiot" has a specific meaning; which you chose to disregard.

Maybe start by reading Manufacturing Consent.

Criticizing your gear? Why would I do that? the D300 was seriously my first digital camera and I used it from when it was released until like 3 years ago when it finally died... And I'm perfectly capable of taking a picture, thank you.

Will Murray's picture

Note that I deleted my comment before you commented. But since we are here; I note again, that you have nothing more to show other than a logo. Until you demonstrate otherwise, you are just another person who can't, so instead spends their time arguing with strangers on the Internet - and I further note you are on multuple forums.

Unless your idea of taking photos are snapshots. Not that there is anything wrong with that, but be honest about it.

michaeljin's picture

Are snapshots not photos?

Will Murray's picture

Oh, without doubt. But let's drop the pretense

michaeljin's picture

What? You want me to post a few pictures of trees in fog and some garbage portraits with way too much headroom? I have plenty of those. Well, not the trees in fog since we don't get too much fog around here (although I do have plenty of snapshots of trees), but I do have plenty of crappy portraits. I've just got enough decency not to subject people to them.

Will Murray's picture

At least I'm making an effort, right?

Oh look, roadkill


michaeljin's picture

Yes, you are making an effort and I applaud you for that. I fear that I've nothing worth posting that I would actually want people to look at.

Will Murray's picture

And the only reason I posted image to my profile is that when these exchanges happen, as often as not the comment is made upon lack of work. The fact that I am not posting in groups says it all. If people want to look, then great, if not also great.

Artistic merit aside, I'm not running a photography business and nothing I've done (photographically) will be remembered. And that's OK.

michaeljin's picture

I AM running a photography business and nothing I've done (photographically) will be remembered either. I think that's OK, too. As long as you're doing things that make you happy. For me, it's the least miserable way I've found (so far) to make a living so I guess I'm cool with that.

Frankly, I wonder who will actually end up being remembered from this era given the glut of talent out there.

Also, the "lack of work" comment that people so often make is just bullshit. There's no logical connection between a person's photographs and the point that they're actually trying to make (unless they happen to be commenting on a technique that they clearly suck at). So I feel you there.

michaeljin's picture

Not that it matters, but I just uploaded some less trollish photos so we're on even ground in that regard. Enjoy.

Will Murray's picture

Interesting work. I really like the portrait of the woman in red. Thanks for sharing.

Will Murray's picture

There was absolutely no reason for this to go here; but you want to engage in arguments on the net...

And remember, I'm not on other forums, but I see you there too.

michaeljin's picture

Can't remember the last time I was on a forum, but OK. I'm guessing you see me on Petapixel or NikonRumors? Unless, of course, you're a creeper and you're stalking me on Major League Soccer.

As for there being absolutely no reason for this to go here, I think it was inevitable given our personalities meeting.

Will Murray's picture

No, I just read comments, and you are impossible to miss; given that you are a complete dick.

michaeljin's picture

This, I will not deny. LOL

Christos Dikos's picture

Good to see at least one camera manufacturer continuing to push the envelope.

michaeljin's picture

I expected the A7SIII to release first so this is certainly a surprise, but the A7RIV looks like a solid camera for sure.

I know, right. People have been talking about the supposed release of the s3 then the r4 like came out of nowhere. :D

Jaleel King's picture

I have to say, this is an expensive piece of gear with an unbelievably short life cycle. I'm honestly happy that Sony is pushing out new gear, but this series, A7r, gets updated every 2yrs? As soon as I got the A7r2 the 3 came out and the A7r3 feels like it was just released. Outside of no longer getting firmware support, I don't understand the rush even vs the A7r2?

Yes, this has "better" ergo and a few other bells but it really makes one wonder is it always better to wait or get used when it comes to the A7 series at this pace? If nothing else maybe I can pick up a used A7r3 for a steal now. Ha!

Eric Salas's picture

If you already have an A7Riii like I do, you really aren’t tempted to upgrade unless you need/want more MPs, better AF, lcd , viewfinder, better ergonomics, eye AF in video... If you don’t have it, this is the best option for someone looking at a high MP count full frame; it’s that simple.

The life cycle of a camera doesn’t just end when an upgrade is made and nothing on the market touches the A7Riii still. You’re just able to get a Riii cheaper now.
