Several years ago I was a podcast producer for fxguide, specifically thevfxshow. Over 100 episodes as a matter of fact. When I was with the fxguide crew in Las Vegas at NAB in 2011 we met and interviewed Lee Peterson who was a lead designer of the Hasselblad cameras that went to the moon on Apollo. The link to the recorded interview is below. Lee is a very interesting person and it was an honor to sit and listen to issues that were faced when designing lenses and cameras that had to work both in atmospheric pressure and in complete vacuum as well as the extreme temperature changes the on the moon. It's worth a listen.
