Im sure that all k-7 users did upgrade their camera but if there were who didn't upgrade yet, you should charge battery fully and format memray card before!
I'm really satisfied with this firmware and now I feel like I have a perfect camera which I was looking for.
Small, light, 1/8000 shutter speed, good high iso(800, I usually don't use After 1000 or 1250) weather sealing, fast live view AF(I don't worry About blurry pics that are taken by other people who don't have slr camera anymore!!) Thanks PENTAX right on. Keep going like this! Now I'd expect much better AF speed and accuracy in indoor.
Very nice firmware update! Love the new "airplane leveler". My DA* 50-135 doesn't focus with contrast autofocus, but then it didn't do that before either so lens issue I guess strange though that phase autofocus works!
