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?
Note: The Sony a7R III “A” variant was announced in April 2021 and is identical to the original model, but with a higher resolution (2.36M-dot) LCD.
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 (although the a7R III “A” version has 2.36M-dots)
- 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.
