Sony's A7R Mark III takes all the good bits of the A9 and makes it cheaper

Comments Comments

The dust has barely settled on the announcement of the game-changing A9, but Sony's relentless development of new camera technology continues apace with today’s announcement of the A7R Mark III. 


The A7RIII appears, on first glance, to be a hybrid between the A7RII and A9 cameras. It features the larger battery, improved EVF and dual card slot of the A9. But for lovers of high IQ it retains the high-resolution sensor of the A7RII, with further improvements to dynamic range.  This will offer huge benefits for those photographers who often find themselves shooting in high, or extreme-contrast situations.

Physically the new A7RIII appears remarkably similar to the two-year-old camera that preceded it. However there are some changes, a joystick for flicking through menus, and a touch-sensitive screen for picking focus points. There's also two SD slots and two USB ports: a microUSB port for accessories, and for charging, a USB-C port. 

The star of the show is the full-frame 42.4-megapixel EXMOR R sensor that means the A7RIII shoots at twice the resolution of Sony's A9.

The new camera is probably best suited to those photographers who admired the specifications of the A9 but would miss the nearly 8K resolution of the A7RII. At 10 frames per second it is no slouch for such an ultra high-resolution camera and acquires most of the AF speed of the A9. The A7RIII has the added benefit that it can do this using either the electronic shutter (with or without the silent option) or a newly improved mechanical shutter.

No prices have been confirmed for Australia yet, but we've heard it will retail in the US for $3,199 when it launches in late November — that's quite a bit cheaper than the A9, and no more expensive than the model it replaces when it first launched.
