Yashica Atoron Electro dd-x 5 lens is a compactThe Yashica Atoron Electro is a subminiature camera designed to shoot Minox film, which is still available from our (presumed) friends or at least non enemies at Blue Moon Camera. Like all Yashicas of the Electro era, this camera uses a battery that doesn't exist any more, but you'll find adapters available (or you can rig one up yourself). Anyway, not super practical, but kind of fun. Includes case and right angle viewing attachment FOR SPYING.
