Olympus E.Zuiko Auto-T 100mm f2.8 &nbsptype_Black & White big-body 35mm SLR that makesThe Olympus OM E. Zuiko Auto T 100mm f2. 8 is a very compact short telephoto lens for the OM mount. In excellent cosmetic condition, this lens has clean glass and good mechanical function. Diaphragm is snappy, but the blades have small dings on the leading edges they don't affect function, but it looks as though the diaphragm has been repaired at some point. Imaging is excellent. A nice lens in good working order, if you don't mind the aperture blades
