By PF Staff in Firmware Updates on Jan 12, 2012

Firmware version 1.12 for the Pentax K-5 has finally been officially released!  As expected, this update only includes stability fixes.

According to the Japanese Pentax site, the following change was made:

• Corrected --- When O-GPS1 is mounted on the K-5 and taking a picture of starry sky with long exposure tracing by ASTROTRACER function, a band of light green noise rarely occur on image depending on photographic condition.

According to other sources, other minor stability issues (such as feezing) have also been addressed via this firmware.  The previous firmware version, 1.11, was released nearly 6 months ago.
