I just found this old camera while visiting with my mom. Apparently my dad bought it in Japan while stationed there during the Viet-Nam war. I did some research on it today, and it seems to be a very good little camera. It shoots any 35mm film, but 2 photos per 1 negative. Each shot is 1/2 the size of the full negative. It's has a fast little 2.8 Zuiko lens. I'm curious if any of you have run into this camera before, and if so, I was wondering about filters for it. According to the manual, which I found online, there are screw in filters available, but it doesn't say what size. If anyone knows, and knows whether or not I can use any old filter, assuming it's the right size, that'd be great. I'd love to get some color filters and shoot b&W with this thing. Here's the manual: http://members.cox.net/minolta16/pen/ I'm shooting a 24 exposure roll of generic ISO 200 color film that my mom had laying around. I can't wait to see what these turn out like. I have to take 48 shots though to finish the roll What a neat little camera. I'd be interested to hear if someone has used one of these before.
