16-mm movie cameras
The 16-mm Maurer Data Acquisition Cameras very small, compact units, slightly smaller than a thick paperback book with their 130-foot film magazine attached, but are adapted to allow operation by a gloved hand. They can be run at 1, 6, 12 or 24 frames per second, allowing up to 87 minutes of filming on a single magazine at 1 frame per second.
The cameras can be powered either via a cable from the CM's 28-volt DC supply or the LM's internal supply, or by an attached battery power pack.(ap15fj)
[edit] Apollo 15
Apollo 15 carries three 16-mm cameras, one for use in the Command Module, and the others stowed in the Lunar Module to be used only during the lunar exploration. Two interchangeable lenses, 18-mm and 75-mm, are carried for the unit carried in the CM while the lunar units have only one 10-mm lens each. (ap15fj)
