Sony readies the A99 Mark II A-mount full-frame camera for action

With a new everything -- body, sensor and autofocus system -- Sony's targeting pro sports photographers with the updated version of its fixed-mirror camera.

I've been reviewing hardware and software, devising testing methodology and handed out buying advice for what seems like forever; I'm currently absorbed by computers and gaming hardware, but previously spent many years concentrating on cameras. I've also volunteered with a cat rescue for over 15 years doing adoptions, designing marketing materials, managing volunteers and, of course, photographing cats.

Editors' note, September 19, 2016: Updated with a correction about the size and comparative specifications.

I liked a lot of things about the Sony A99, the company's fixed-mirror full-frame dSLR-style camera, but it's sat around for over three years while competitors have introduced improved models. Sony finally succeeds it with the A99 Mark II, bringing all of its A-game technologies with the hopes of attracting professional action photographers.

It incorporates the same 42.4MP Exmor R CMOS that's in the excellent A7R II mirrorless. There's also a new adaptation of its 4D Focus hybrid autofocus system with 399 phase-detection AF points on the sensor in addition to a separate module with 70 points, for 79 cross-type and sensitivity down to -4 EV. Five-axis sensor-shift stabilization and 4K uncompressed video with all Sony's bells and whistles complete the package. The body is slightly smaller than before and is still dust- and moisture-resistant.

Unfortunately, the battery life is still miserable for a professional camera: 390 shots with the viewfinder and 490 shots via the LCD. That means you'll probably need the battery grip, which defeats the purpose of shrinking the camera body. It also still has dual SD card slots, which is ironic given that the much faster XQD format, used by Nikon in the D5 and D500, is Sony's.

Sony plans to ship it in November at $3,200 for the body. I don't have UK or Australian pricing yet, but that directly converts to about £2,450 and AU$4,240.
