The X-30 is a camera for recording x-ray images on a fluorescent screen, made by Mamiya in the 1950s. It is a rather simple camera; there is no shutter, just a dark slide inserted in a slot in the top plate of the camera body. In practice the exposure might be controlled by the opening and closing of the x-ray source. The lens is a 6.5cm f/1.4 Roentgen-Zunow, mounted in a plate to fasten into the display of the x-ray machine, and with a fine-focusing control but no iris diaphragm. No viewfinder is required. The camera body attaches to the back of the lens with a bayonet. An example seen at Westlicht comprises the lens, two camera bodies and ten film cassettes (by Canon) in a wooden outfit case fitted to exactly this set.[1]
The camera body has an advance knob with a chain wrapped around it, allowing it to be advanced (once) by pulling a string tied to the chain, from behind the x-ray protection screen. The dimensions of the exposed film-frame are not certain: there is a frame-counter scaled up to 50, so it could easily be a square frame. There is a simple crank for rewinding.
