I'm on vacation and noticed that my parents have this very strange looking polaroid camera. It says something like "mp3 industrial view camera". I can't find anything about it online because all searches for mp3 and camera bring up other things. I originally brought it home from when I was cleaning out the physics department during my college job and couldn't stand to throw it away. I didn't know what it was and still don't really. Also, it has a tominon 127mm lens in a copal shutter. Is this a decent lens and does it cover 4x5? I'd start using it right now but I can't test it for coverage.
