Originally posted by Christopher M.W.T I can't imagine it been much more than a firmware update? I find it hard to believe the Q would have a more powerful processor than the K5.
It certainly is firmware only.
The Q has the same video mode dial position (conflicting with the M mode position) and less buttons. Everything else is software.
Adding manual controls to video for the Q must have been an afterthought. Otherwise, the Q would have gotten a video button (a separate red record button) rather than a mode dial position which is awkward anyway. Esp. if you later want to allow stills during video.
So, the question if there now will be a manual video mode firmware upgrade for the K-5 tells us a lot about what Pentax thinks about their customers ...
