The Opema II is a 24×32mm camera made by the Czech company Meopta in the 1950s. It has a focal-plane shutter with speeds B, 25–500 and interchangeable lenses, and existed in two versions. The Opema I has a viewfinder only, and the Opema II has a coupled rangefinder combined with the viewfinder. The lens mount is a 38mm diameter screw mount that may look the same as the 39mm Leica screw mount but is crucially different and unique to the Opema. Attempting to mate a 39mm screw lens with an Opema (or a Meopta lens with a Leica or other screw-mount body) risks stripping one or both threads. This Opema II is in excellent working condition , shutter is working on all speeds but not tested for accuracy. The lens looks clear and without scratches on the glass. The lens can be screwed off ,note that the screw thread is 38mm and not 39mm which is Leica thread.The rangefinder is coupled and looks clear and accurate . The top cover looks if the Chrome is polished off . Please see all pictures as they are part of the description.
