That's my Kowa. She has a great lens. I love the light meter - and it takes no batteries - which is a major plus.
It has this really odd habit of wanting to expose the film and forward at the same time. The shutter button doesn't stick...until that odd habit takes over and it won't release the shutter unless I'm forwarding film. It does this with and without film in the camera.
What does this? Any ideas?
