This is a nice & sharp Vivitar Series-1 90mm f2.5 Macro manual focus lens in Canon FD mount in excellent+ condition!  The lens shows some minor wear from normal use with a stuck filter which doesn't affect lens operation. The glass optics are clean with no scratches, marks or fungus with some internal dust and may have slight haze. It focuses smoothly and the aperture works properly with no problems. This is a sharp 1:2 Macro lens that will focus down to a 1:1 magnification ratio when used with the extension tube great for close-up photography! It can also be used as a regular telephoto lens great for portrait and everyday use! A beautiful lens to work on Canon manual focus film camera including A-1 AE-1 T90 etc.! (may 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 $15 within the US or $38 for other international destinations.
