Minox in the Movies - Knight Rider Minox B

In this short clip from the TV show Knight Rider, a woman breaks into a safe in a Las Vegas casino office so she can photograph the blueprints for a proprietary computer chip. The scene is brief but you can see she is using a Minox B, although her fingers seem to be obscuring the lens.
