Actually, I don't know if ricehigh is an expert or not, and don't care. He/she obviously knows alot about the insides of Pentax cameras - guess if you are into disassembling Pentax firmware, go for it. I appreciate the tutorial on how to get the debug stuff to work.
The debug menu worked on the K-x, and I was able to fix the front focus. Dialed in -70 um's, and the front/back focus is pretty darn close on my lenses. Why don't they do this at the factory? (rhetorical question) Unfortunately, I sent the 40mm ltd back already - that's ok, I can always get one in the future.
Some pix from the kit 18-55, and the 21 ltd, in extremely challenging light - shooting almost directly south, into the sun. Even with a polarizer, still some flare. Mt Hood in the background, the Columbia river gorge and the Bonneville Dam complex, from the top of Table Mountain.
K-x is an awesome camera, and now it auto focuses properly
Of course, today was very bright, and not a good test of the focus, but still a gorgeous day to get out and shoot some pictures.
