Pentax Japan has released a new firmware, Version 1.12, for the K-5 digital SLR camera. The updated firmware addresses the rare issue when shooting a starry sky.
Pentax said, “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 occurs on image depending on photographic condition.” This has been corrected with Firmware v1.12.
The new firmware may be downloaded from the link below.
