Hi,
ICM, a Russian Company made a set of Panzer crewman in 1/35 scale for diorama purposes. The poses are such that the crew pose in front of a Panzer while one of the figures hold a camera and takes a snapshot of the crew. It was one kit in a series of panzer crews at different stages of the war.
The scratchbuilt option is quite open. Kodak Brownie cameras were widely used by soldiers to take photographs since WWI. Moviecameras of the time was basically a rectangular box with a lens and two reel housings on top on a tripod. It should be easy to make. I'll check to see if I have any pic's I can download for you. Also check out the Time/Life series of books on WWII. They have a couple of photo's of cameramen in action.
Good luck,
Tappie
