Canon 200mm f/4

{"overview":"The Canon FD 200mm f\/4 is a manual-focus medium telephoto prime for Canon's FD breech-lock and later bayonet FD mount, introduced as part of the FD system that ran from 1971 to 1987. Later bayonet-mount FDn versions in clean cosmetic condition typically command a small premium over earlier breech-lock examples when they appear.","buying_guide":"Inspect the front and rear elements for fungus, haze and cleaning marks, and angle the lens to the light to check for any coating scratches or early signs of separation in the cemented groups. Work the focus ring through its full travel to confirm it is smooth rather than stiff or gritty, and stop the aperture down to check the blades open and close crisply with no oil residue.
