I was watching a show on the local educational network about a team who goes around freeing whales from fishing nets, and they showed one of them taking stills. He was using a Pentax 645 (don't ask me what model).
I always get excited when I see a Pentax on TV... regards, frank -- "The optimist thinks this is the best of all possible worlds. The pessimist fears it is true." -J. Robert Oppenheimer
