The lens is a 50mm Bausch-Lomb Tessar Series 1C, Patented February 24, 1903. The lens iris is smooth and moves easily through out the complete range of stops, from F 3.5 to F 32. The focus is smooth through its entire range. The camera mechanism is the same as the very first Lumiere Brothers cameras. That was the first commercial motion picture camera movement designed and manufactured around 1896. This is a working motion picture camera and will shoot today. It will use today's film as film sprocket holes were standardized about six years before this camera was
manufactured and the same standards have been in continuous use ever since.
