Thanks for the responses, everyone (and shady, for elaborating on your response).
Originally posted by stevebrot It appears that the only restriction with your K-series lenses are that only Av and M modes are supported.
Oh fer pete's sake. I didn't switch the camera to manual mode! m(-_-)m (bakadakara)
The camera wasn't in great shape overall. The flash refused to stay up, for instance. Japan is a country where used gear is generally in great shape but for some reason used and abused models are turning up more frequently recently. It could be that people are selling off stuff they know to be poor condition to raise a few ¥. The economy here has gone from flat to "downward spiral".
I'll check out the manual, thanks for the tip. The camera felt great in hand and the viewfinder was nicely wide and bright.
