Last K-5 picture for a while - right after I took this picture I went to change lenses. Something was missing - the lens release button. Sigh! Spent this evening digging out a bunch of paperwork to send it in for extended warranty repair. I think this is the first time I've actually used an extended warranty (I don't normally buy them, and this is the first time I've actually used one). I hope it won't take them long to fix it. Luckily I have a back-up camera
