Pentax K-1 Firmware v1.43 Released

Stability improvement over prior firmware

By PF Staff in Firmware Updates on Nov 10, 2017

Ricoh Imaging has just released a new firmware update for the Pentax K-1.  This update addresses an stability issue introduced in the prior firmware update, v1.42, which itself patched an issue from the previous firmware version. 

There are no new features in this firmware update, but as always, it includes the contents of all previous updates (many of which were feature-enhancing).  We therefore recommend the update for all current K-1 users.

Download the K-1 firmware from the official Pentax firmware site.

Ricoh Imaging has just released a new feature-enhancing firmware update for the Pentax 645Z, which follows in the footsteps of other recent updates that focus on keeping the functionality of top-tier models current.

This update includes features that further enhance user-friendliness for astrophotography and when shooting in strong sunlight.  Like all Pentax firmware updates, it is cumulative and also includes the contents of all previous updates.

This updates adds the following two features which originally debuted on the new Pentax K-70 and Pentax K-1, respectively:

  • LCD Night Vision Mode
    The backlight is dimmed and the LCD adopts a red color palette to allow you to operate the camera in darkness without being blinded.

  • LCD Outdoor View Setting
    Allows the LCD backlight to be quickly dimmed or made brighter to make it easier to see in the dark or in harsh sunlight, respectively.

A supplement to the user manual, which describes these new functions, has been published online.
