Battery Fit Ricoh
Film Camera…problem..?

I just recently bought a RICOH k4-30sp 35mm film camera in a pawn shop. It came with a lens on it, but the lens in a Sigma lens, but fits on and focuses and everything. Well today is the first day i’ve put batteries in it and tried to use it and everything, well…the rewind lever you pull before every picture wont go back unless i take off the lens, then rewind, then put the lens back on…and sometimes it’ll go completely black….is this a compatibility issue? or is there some sort of trick..i really need to know, its for a class.

I’ve had several 35mm film cameras (Nikon and Canon) and have never seen this. It sounds like a lens issue.
