Happy camera repairing/modding/hacking or whatsoever, no matter what! ;-D
Anyway, unfortunately, the Pentax-Hack does not update any new (hacking) information for newer Pentax DSLR models anymore, neither on the hardware disassembly/repair/adjustment/calibration nor about software/firmware hacks and tricks! Too bad.. :-( Maybe the source of theirs was fired already? :-o
