Sony A7R mkIV Announced | Still A Generation Ahead Of The Competition

By Matthew Saville on July 16th 2019

Today Sony Electronics has announced their next high-resolution flagship camera, the Sony A7R IV (mk4). Replacing the A7R III (mk3) in its lineup, it boasts a 61 megapixel sensor, 10 FPS with autofocus, Real-Time Tracking for stills and Eye AF for both photo and video, a 5.76M dot OLED viewfinder, plus, allegedly, the best dynamic range of any Sony camera, ever.

At first, outwardly it may not look like it is that different from the previous generation A7R III. However, if you look more closely, you’ll notice that a few of the buttons have been significantly redesigned. Plus, under the hood, Sony states that they have yet again improved the overall weather sealing and build quality, including a better grip. Simply put, this camera could be a whole lot more than just a few more megapixels compared to its predecessor!

Sony A7R IV | Matt’s Gut Reaction (Armchair Review)

This is the writing on the wall that I saw about four years ago, as I was reviewing the Sony A7R2. Was it a perfect camera? No, but it was clear that Sony engineers were doing everything they could to overcome the main obstacles that mirrorless cameras faced at the time. They were figuring out how to make on-sensor hybrid autofocus better than traditional off-sensor PDAF. They were improving the viewfinder lag time and resolution. They were “cramming in more megapixels”, while still achieving shockingly good image quality both in terms of base ISO dynamic range and high ISO noise levels. It was unprecedented in 2015, and it is finally showing in their latest camera generation today. Why? Because, to be totally honest, the A7R3 was already so damn good that it was an easy recommendation to make for many types of photographers. From landscapes to portraits, if you wanted that resolution, the A7R III was already a top choice.

And now, Sony is another generation ahead of everybody else. Obviously, this isn’t a final review and I haven’t held the camera yet, but unless we live in some sort of bizarre twilight zone, the mk4 will offer noticeable or even substantial improvements over the mk3 in pretty much every regard, from autofocus to image quality. Meaning Canon and Nikon have yet another whole generation of catching up to do in those regards.

Look at the A7R4’s awesome AF-ON button and AF point control pad!

Finally, it also appears as if Sony is tackling one of the last remaining issues that I’ve always had when I pick up an A7-series camera: They’ve redesigned the ergonomics, so that the camera is still familiar to those who already know the 7-series, but also so that it appears a lot better. Namely, the rear AF point joystick looks like a nice big knurly bump, instead of a smaller little nub, and the AF-ON button looks huge!

Never judge a book by its cover, of course. On paper, there is a lot going for this camera. But, my prediction? You get your pre-orders in now! (We’ll update this post as pre-order information becomes available!)

The Sony A7R4 will be available in September for $3500.
