This is a classic manual focus telephoto prime lens from Canon, released in the 1970s-80s, designed for the Film-era FD/FDn mount. 1. Excellent optical performance of a prime telephoto lens: The 200mm fixed focal length delivers sharper images compared to zoom lenses. The maximum aperture of f/4 is neither too bright nor too dark, allowing for moderate bokeh. The in-focus areas are very sharp, capturing fine details in portraits and landscapes. [Grade] Good / Very good condition, with some signs of use. [Appearance] Clean, but with some scratches from use. No stickiness. Please check the photos for details. [Functionality] Works perfectly. [Optical System] Slight traces of mold on the rear ball part, but does not affect the photos. No haze No scratches No marks No balsam separation Minor dust (does not affect photos) [Included] Front cap Rear cap Thank you for viewing.
