Canon 20mm f/2.8

{"overview":"The Canon FD 20mm f\/2.8 is a manual-focus ultra-wide-angle prime for Canon's FD bayonet system, produced during the FD era (1971–1987). Because these are wholesale auction results rather than retail, clean dealer-listed copies typically sell for more, and the price a user-grade example fetches depends heavily on glass and aperture condition.","buying_guide":"Inspect the front and rear elements for fungus, haze and coating scratches, as ultra-wides of this vintage often show cleaning marks on the bulbous front. Work the aperture ring through every stop and check the blades are dry and snappy — oil migration from the focus helicoid is a common FD-era issue — and confirm focus is smooth without stiffness or grit.
