Pentax has issued a firmware update for its K-30
cameras that fixes an issue caused by the previous update.
Firmware version 1.03 fixes an issue caused by the previous firmware update, version 1.02, that meant contrast AF did not work for some lenses when recording movies.
The firmware update is only necessary if you have installed firmware version 1.02.
Pentax have apologised for any inconvenience caused.
