Pentax K-3 III Firmware Update v1.31 Released

Ricoh Imaging has released a firmware update for the Pentax K-3 III which adds a new custom image preset called "Satobi".  This preset delivers slightly muted colors similar to early film prints, delivering an artistic nostalgic effect.

In addition, a tone curve will now be displayed for each preset in the custom image menu.

These features will be coming to the Pentax K-1 and K-1 II in the near future.

Download the K-3 III firmware from the official Pentax firmware site.
