Vintage Canon Lens - - A vintage Canon Mirror Box 2 and one Canon 135 mm camera lens complete with lens caps and original leather Canon transport bag, (circa 1960's). The Mirror-Box 2 was established to connect the 2.5/135mm lens and any longer lens to the Canon 7 rangefinder camera. It includes a prism with upright, non-reversed view and a bright fresnell screen.The box is connected to the outer bayonet mount of the Canon 7 in a way similar to the 0.95/50mm lens, and the lenses are mounted to the box in the same way. The system operates without cabling, by pressing the trigger arm, the mirror moves upward out of the way (no rotation), then the camera is released. The mirror stays open after exposure (no instant return mirror). The small lever next to the self timer lever when mounted, will return it to the down position. The Canon 135mm lens was one of the highest quality lens that exisited in the early 1960's, and one of the most complex optical designs in this focal length of its time. For example, Leica had a 135mm f/2.8. Nikon had a 2.8/135 consisting of 4 elements since 1965, making this Canon lens an engineering marvel of it's time. Condition: Used/Good, very well kept considering it's age, no scratches or structural demage to the lens, no fungus inside, overall very good.
