Hey! I've been a lurker here for long enough and the K-5 release just sorta convinced me to finally make an account.
I've been using my K100D for at least 3 years and before that, I got a chance to use a K10D before my father took it with him to China. I've recently gotten hooked on all-manual primes but the K100d's lack of higher level functionality drives me nuts at times.
Oh yeah, I forgot to mention that my K100D has a nice nick in the sensor cover from a cleaning mishap >_<"
