Petapixel reports that the firmware update version 2.1 that Sony released today for the a7 III and a7R III cameras fixes the issues that were inherent with version 2.0 that was released in October. The earlier version was found to cause data loss in some specific circumstances and was removed from Sony’s update server shortly after it was released.
Nauticam has announced their housing for the Sony A7RIII mirrorless camera. It is compatible with the company’s N100 port and accessory lenses and offers strobe triggering via fiber optic (with optional flash trigger). Levers allow for access to “essential camera parameter changes” from the handles.
Sony has announced their new full frame mirrorless camera. The a7R III features a 42.4 MP sensor linked to an updated BIONZ X processing engine, offering a native ISO range of 100-32000. Autofocus has been improved and 4K video is available from the full width of the sensor. Of interest for underwater use is that battery life has been more than doubled over that of the a7R II.
