Pentax K-1 Firmware v1.20 Released
Adds KAF4 mount support
By PF Staff in Firmware Updates on Aug 4, 2016
Ricoh Imaging has just released its second firmware update for the Pentax K-1. As promised at the time of the launch of the new KAF4 lens mount, the update enables the camera to control the aperture of KAF4 lenses, which use an electromagnetic diaphragm rather than the traditional stop-down lever.
The (APS-C format) DA 55-300mm F4.5-6.3 ED PLM WR RE is currently the only lens with the KAF4 mount. It is due for release shortly.
Download the K-1 firmware from the official Pentax firmware site.
