I was in charge of picking the movie a couple nights back, after a run of rom-coms chosen by my girlfriend. So, of course, I picked a Mystery Science Theatre 3000, called "Gamera."
Attached are some screen shots of what looks to be a fairly early Canon with a 135mm chrome lens. He was a reporter figure, and later in the movie, had found a gigantic shoulder-mounted cine camera.
Not captured was a Graflex that supposedly lived on a research boat in the Antarctic, right after the giant turtle appears.
