My K 5 has locked up. The train of events: Saturday night I checked the charge state of the battery in the body and in the hand grip. Both good. The memory card had 91 RAW images remaining. Sunday morning I went to a water fowl rookery in Port Royal, SC to shoot the birds. Mounted my Sigma 135 - 400 zoom to my tripod, mounted the K 5 to the lens, plugged in a wired remote release, and turned the camera on. The top screen showed no response to changing shutter or aperture, no change in ISO. I turned the camera off, then back on. Still no response to the wheels. I tried an exposure, and the camera locked up. Mirror locked up, top screen blank. Nothing. Back at our son's house I removed both batteries, and reinserted them. The mirror returned, I tried a shot. Mirror lockup, no top screen, nothing happening. Home here in Georgia I've done the battery thing again, but no luck. Looking at the pdf of the manual the index mentions "Reset," but that of course requires access to the Menu. Anyone have any ideas, or do I now have a paperweight. I suspect that a repair would cost more than the cost of a second hand K 5.
