If you’re using a Pentax interchangeable-lens camera made in the last few years, the company has released new firmware for DSLR and Mirrorless cameras.
The new firmware covers K-mount digital SLR cameras, as well as the K-01 compact system camera. Pentax notes that it has “improved stability for general performance” for each camera.
More details and the firmware updates for all six cameras can be found on the Pentax Ricoh Imaging software downloads page.
