The a7R III takes Sony's proven high-resolution full-frame mirrorless camera and improves upon its speed, autofocus system, and video capabilities.

  • +

    Proven 42MP full-frame sensor. Improved processor and autofocus system. 10fps image capture with tracking. Silent shooting option. Tilting touch LCD. Dual card slots. Larger battery than a7R II.

  • -

    Only one card slot supports UHS-II speeds. No built-in flash. No in-camera time-lapse support. Can't start video until image buffer is cleared. Dense menu system.

It's fair to say that the Sony a7R III is a great option for an incredibly wide variety of photographers. Offering great image quality, fast burst shooting speeds, high quality 4K video and a reasonably compact package, it's an incredibly well-rounded offering.

  • +

    Hybrid stills and video shooters, photographers looking for a versatile tool for a wide range of subjects in a compact package.

  • -

    Those that need the absolute best in autofocus tracking, those that require even faster burst speeds.

Sadly, we weren’t able to test one of the headline features of the A7R Mark III: Pixel Shift Multi Shooting. It is similar to the High Res Shot mode found in some Olympus Cameras and the Pixel Shift Resolution mode in several Pentax DSLRs.

  • +

    42.4MP full-frame sensor, 10 FPS burst shooting, Vastly improved battery life, Improved image stabilization, Improved AF performance

  • -

    No “anti-distortion shutter” rating, Burst mode limits compressed RAWs to 12-bit

Sony's Alpha A7r Mark III is a highly capable camera that's equally at home shooting high resolution stills as it is handling fast action or filming quality video. The 42 Megapixel full-frame sensor may be inherited from the Mark II but Sony's improved the processing to deliver superb quality.

The Sony A7R III sees improvements in pretty much every area: physical design features, image quality, speed and performance, as well as video recording capabilities and battery life.

  • +

    Fantastic image quality; Improved dynamic range over its predecessor; Very good high ISO performance; Much improved real-world AF performance; Class-leading burst rates, even with RAW; Improved 5-axis in-body image stabilization; Better 4K video quality; 1080/120fps video; Dual card slots;...

  • -

    Expensive; Menus still confusing; UHS-II support only on one card slot; No optical low-pass filter means greater risk of moire; No built-in flash; Buffer clearing still slow despite UHS-II support.

The Sony Alpha A7R III is easily one of the best cameras you can buy at the moment. Here is our detailed review of Sony Alpha A7R III.

When Sony unveiled its top-tier flagship full-frame A9 , we wondered when the camera’s top-tier features would trickle down to lower-priced models. Surprisingly enough Sony didn’t take long to announce the A7R III, which had many of the same features that made the A9 great in a slightly cheaper...

On paper, Sony's $3,200 full-frame mirrorless Alpha A7R III is a beast. With an ultra-high-res 42.4-megapixel sensor that can shoot bursts at 10 fps, you can capture landscape photos one day and sports the next.

6 April 2018

The best camera that Sony has ever made. This one goes toe to toe with Canon or Nikon’s finest.

  • +

    42.2MP at 10fps, 5-axis IS system, Fast autofocus

  • -

    Battery could be better

A great camera with a few flaws that has really taken it up to the big boys in the top end full-frame DSLR market. Has every right to be considered a major contender by anybody looking to move into high end hardware. Will convert some pro photographers to mirrorless full-frame but I suspect not all.

  • +

    Image quality, image quality, image quality – fabulous!, Flexibility – will suit wedding, events, street and landscape photographers in particular, Impressive autofocus performance, Much improved battery life, A market leader in full-frame, interchangeable lens, mirrorless cameras, Great viewfinder...

    Too complicated – the menus, in particular, are very difficult to work out, Very expensive – and as such asks a big question, Very slow in clearing image buffer, The grip could be a little wider (particularly if hefting a large telephoto lens around), UHS-II cards supported in only one of the two SD...

I have owned both of this camera's predecessors, the A7r, and the A7rii. The A7r was good but glitchy with a poor selection of lenses. The A7rii dealt with most glitches and more good lenses became available. The A7rii was a major upgrade.

19 February 2018

Edges out the Nikon D850 as the best camera made today. I use Sony G-Master lenses attached to this camera and I get fast auto focus, high resolution, 4K video, and low noise at high ISO levels. There are a hundred other functions that this camera is capable of which might be useful to others.

  • +

    High Resolution, 4K Video, Low Noise at High ISO, Fast Auto Focus.

Sony continues to dominate the camera market right now with its advanced technology packed in to an ultra-compact body, and all at a resonable price. The Sony a7R III is no exception and is considered by many experts as the best all-around camera on the market right now.

Since the beginning of the original NEX introduction I predicted that the "NEX" concept will be the next big thing, and I have been using Nex-7, A7, A7R, A7R2, A7S2, and now A9 and A7R3, and after few months and about 30-40k images with A7R3 I think it is time to do a short review.

Coming from the a6500 which is also a great camera, I love the placement of the buttons much better. Feels more natural.

EXCELLENT!As this body has met, even exceeded, my expectations, I will now sell my entire Nikon inventory and concentrate on Sony.The A7R-III replaces my D810 and joins my Sony video cameras with E-mount lenses, of which I have many primes.

Having owned and used 2 other Sony mirrorless cameras, I sort of knew what I was getting into here. I loved the idea of having the same great camera that I've been used to, only with improvements and greater features. I look forward to doing more with the 42mp, and the greater dynamic range.

Sony fixed a laundry list of issues that plagued the a7R ii (ie: battery life, slow write speed, finicky eye AF, etc)What still needs fixing: AWB (not reliable, needs to be set manually), unnatural colors at times (usually due to incorrect AWB), menu has poor UI/UX, keep photo and video settings...

Who can't love 42 megapixels?!Set to "AUTO" it is amazing.I can't bother with a 650-page user manual. The manual however is on my computer.Using it for now with my old Leica-M lenses with good results.

There is nothing on the market at this price point that even comes close to the specs and quality of this camera! Did a birthday shoot over the weekend and I was very happy. Some low light photos had a bit more noise than I would have liked, but I was using a Cannon 24-105 with the sigma MC-11...
