Pentax has released new firmware for its flagship K1 full frame camera that includes the ability for users to select electronic shutter shooting for the first time. Firmware version 1.3 adds a live view Electronic Shutter option to the menu system that the company says avoids the vibrations caused by mechanical shutter actions immediately prior to the exposure of the sensor. There are some limitations however, as the shake reduction system can’t operate during electronic shutter exposures, HDR mode won’t work, external flash units won’t be triggered and the drive is limited to single shot or multiple exposure modes.

Other functions added by this update include the ability to shoot square images and to record only two frames (Off and Type 2) when using the anti-aliasing filter simulation bracketing feature. Previously, three frames had to be recorded in a sequence that included Type 1 as well. A general ‘bracketing cancel’ Off option has also been added to the camera menu under the BKT function.

Pentax says that other more general stability issues are fixed too with this update. To read more and to download the firmware see the Pentax website.
