Sony a7R III Overview

The Sony a7R III was announced on October 25th and I placed my order on the first day because it sounded like a big step-up from my trusty Sony a7R II, but was this a mistake?

It certainly wasn’t a mistake and the a7R III proved itself to be a very capable all-rounder that could excel itself in many different niches.

Here are some of the things that the a7R III shares in common with its predecessor the Sony a7R II:

  • 42.4MP 35mm full-frame Exmor R CMOS and enhanced processing system
  • 5 axis stabilization
  • 399 phase detection points
  • ISO 100-32000 range (50-102400 extended)
  • 4K movie recording up to 30fps

And here are the new features that the a7R III gains:

  • AF joystick and larger buttons with improved tactile feedback
  • Larger NP-FZ100 battery
  • Improved menus and menu customization
  • 3.69M-dot (1280 x 960 pixel) OLED viewfinder
  • 1.44M-dot rear touchscreen LCD
  • Real-time Eye AF and animal Eye AF with firmware v3.00
  • Pixel Shift Multi Shooting
  • Improved mechanical shutter
  • 14 bit RAW when using the electronic shutter
  • S-Log3 and HLG video
  • Dual SD card slots

DPReview awarded this camera their Gold Award and concluded their in-depth review with the following:

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. The endless customization options can be daunting at first, but in the end, it’s a camera equally at home capturing fast action one moment, and expansive landscapes the next.

DPReview

I’ve primarily used my Sony a7R III for shooting wildlife but it also makes a fantastic camera for aviation photography thanks to the improved autofocus performance.

Although the Sony a7R IV is now available, the a7R III still remains a very popular choice for Alpha Shooters and a great all-round camera.

About Timothy Mayo

I love shooting wildlife the most but will happily point my camera at pretty much anything. I started Alpha Shooters in 2017 to share my own photographic journey and experiences shooting with Sony Alpha. The site has since evolved into a popular community and resource. You can also find out more about my story here or follow me on Instagram if you wish. I also have a YouTube Channel but haven't published much content over the past year due to spending more time changing smelly nappies and also launching our community forums. However, I do plan to get back to creating content for YouTube in 2021!
