This is a nice & hard to find Vivitar 55mm f2.8 manual Close Focusing Macro lens in Olympus OM mount in exceptional condition! The lens hardly shows wear and the glass optics are also clean with no scratches, marks, fungus or dirt. It focuses smoothly and the aperture works properly with no problems. This is a sharp Macro lens (made by Komine Japan) that will provide up to a 1:1 magnification ratio great for macro photography as well as everyday use to work on Olympus OM manual focus camera! (will also work on digital cameras with proper adapter) I have a money back return policy if not satisfied so buy with confidence. Shipping will cost $10 within the US or $25 for other international destinations.
