PRODUCT DESCRIPTION This is one of the original set of 3 bellows macro lenses for the Olympus OM system and was first produced in 1972. It was the first lens from any manufacturer that was designed for life-size reproduction with a 35mm SLR camera. Unlike nearly all of the other OM lenses, this one has a preset manual diaphragm instead of an automatic one, and so exposure has to be measured with the lens stopped down. Focusing is easier with the aperture wide open. Like the other 2 manual macro lenses, the aperture scale appears upside down when viewed from behind the camera. This is because this lens was expected to be used pointing downwards on a copy stand or a macro stand, so that the scale appears right way up when viewed from the front.
