Released in 2017, Sony‘s original A9 Mark II was the first camera to really show that mirrorless could compete with DSLRs when it came to fast autofocus, and it remains a mightily impressive camera to use if your subjects are on the go. Yet while the SONY A9 Mark II initially appears to offer just a few minor tweaks to a winning formula, that’s not quite the case.

Which leads us to the SONY A9 Mark II, announced in late 2019 seemingly in time for the 2020 Tokyo Olympics. Sony says there are a whopping 43 improvements over the original model in total, but just how much difference do they make? I spent a month with the SONY A9 Mark II to find out, testing it with portraiture, landscapes, adventure photography and wildlife while on holiday in Germany.


Although at first glance the external control layout and body look much the same as before, there are some subtle differences on the A9 II. Like with the A7RIV, there’s now a larger and deeper handgrip and a more prominent AF-ON button, and the A9 II also inherits the handy multi selector textured joystick from that camera too, as well as gaining an exposure compensation dial lock.


You get two dedicated UHS-II card slots, but I can understand some of you might have been holding out for the faster CFExpress format, which both the newly announced Canon 1 DX Mark III and upcoming Nikon D6 will use. But otherwise, things are pretty similar to the A9 which means that most A-series users will feel right at home with the SONY A9 Mark II.

A note on the weather sealing. Sony have upgraded the doors for the battery compartment and memory card slots, and these now use a sealed sliding mechanism as opposed to the latch type on the A9. I have to admit the A9 II was put through its paces for this review, experiencing heavy rain and hail while strapped to my pack in the alpine areas of the South Germany, and salt spray on the Eastsea coast. Throughout, it performed admirably.


It’s under the hood where the biggest changes have been made. Despite the camera using the same 24.2MP sensor and Bionz X processor as the original Sony A9, the processor has been tweaked to improve the autofocus algorithms.
So although the A9 II offers the same 20fps for up to 241 RAW or 362 JPEGs with no blackout, and the same 693 focal plane phase detection AF points that cover approximately 93% of the frame, there’s now Sony‘s Real-time AF tracking in a system Sony says makes up to 60 AF calculations per second.

The mechanical shutter, now rated to an impressive 500,000 cycles, is twice as fast when compared to the A9, now shooting at 10 fps. It might not sound like much, but this can make a big difference to photography shot in indoor venues under LED lighting, just the kind of conditions many photographers will find themselves in Tokyo later this year.

Speaking of which, the mechanical shutter also gains the benefits of a new anti-flicker mode that detects fluorescent lighting and adjusts exposure accordingly, although this is unfortunately exclusive to the mechanical shutter only.


It may be a three-year-old sensor, but image quality is still excellent. Images are sharp, full of detail and have good dynamic range even in darker areas. With ISO sensitivity of 50 to 204,800, noise performance is also respectable. I found I could shoot comfortably up to ISO 6400 before noise became noticeable, but even then, detail loss was marginal.


The A9 II‘s video feature set is almost identical to that of the SONY A9 Mark II, which means UHD 4K (3840 x 2160) up to 30p with 60 to 100 Mb/s bitrate and Full HD (1920 x 1080) up to 120p with 50 to 100 Mb/s bitrate. The major addition is Sony’s real-time tracking is now available in video, which works very effectively.

At first glance, the new Sony A9 II doesn’t appear to offer much over its predecessor, but when you move past the sensor and look under the hood, you’ll find a camera that is faster, more refined and arguably much more versatile than the camera it succeeds.

Combine this with the number of professional level lenses Sony have released since 2017, and the SONY A9 Mark II is a very compelling package for a photographer who demands speed and efficiency above all else.
