It seems to be an issue with the digitals and certain F and FA lenses. It's the first I'd heard of it but makes me warry of the new camera (K10D). Hopefully the K series digitals won't have these compadibilty issues since no one's mentioned the issue on the K cameras yet. But, they're brand new, so it's too early to tell. -Brendan __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
