This is an older model, breech-lock Canon FD 85 1.8 lens. Anyone familiar w/ FD gear will know how good these lenses are. Excellent for portraits, and sharp as a tack by f4. The older breech-locks are heavier than the New FD lenses, but the build quality is really nice. This one is bargain priced due to some coating loss/cleaning marks on the front element that have no effect on anything, and the exterior cosmetics show scuffs and wear. Otherwise, no noticeable scratches on the optics, no haze, no fungus, clean blades, smooth focus and aperture clicks. $100 plus $13 shipping within the continental US by insured priority mail. US sale only, and please have a confirmed Paypal address.
