Today is a Sony announcement day that sees the unveiling of the Sony a7R III and 24-105mm f4 zoom, and the announcement of an upcoming 400m f2.8 G Master lens.
The wait is over: Sony has finally unveiled the first in the new generation of the A7 series. As always, the Sony a7R III comes at the vanguard of the new announcements – ahead of the A7 and S models – and this time brings a host of improvements to existing features and a few new surprises.
As expected, the new Sony a7R III brings a high pixel-count sensor, with its 42.4MP of resolution once again making this the model aimed primarily at professional stills photographers. The camera’s back-illuminated Exmor R and BIONZ X processor make this model capable of capturing 10 still frames per second, for a buffer of 76 continuous compressed RAW or JPEG images. ISO is available from 100-32000, and Sony claims that noise has been reduced by up to a full stop.
All of this with the advanced autofocus capabilities we have come to expect from this line’s R model, thanks to its 399 phase-detection AF points across 68% of the image, in addition to 425 contrast-detection points. Sony also claims that the camera’s Eye AF performance has been improved when the subject is moving, backlit or looking down.
What about video?
Just like with the II, the new Sony a7R III is capable of recording internal 4K in both full-frame and Super 35mm modes. As you may remember from some of our camera tests of the previous generation, the A7R II offered a better 4K image in crop mode, so it remains to be seen whether this will still be the case with the a7R III (take a look at some comparisons here, and our review here). It’s worth mentioning that the camera also supports proxy recording for easier editing of high-resolution videos, particularly useful when dealing with the relatively processor-intensive XAVC codec. Additionally, one of the biggest improvements to the video capabilities of the camera is the ability to achieve an increased resolution of 5K in Super 35mm mode thanks to an oversampling of a 15MP section of the sensor.
