Budget Soligor 400mm super-telephoto for Canon FD, cheapest way to genuine 400mm reach in the FD system.
The Soligor 400mm f/6.3 Tele Auto is a budget super-telephoto prime in Canon FD mount, providing 400mm reach at the lowest possible cost for the FD system. The f/6.3 aperture keeps the lens compact and affordable while accepting the trade-off of a dark viewfinder and limited low-light capability.
The 400mm focal length provides genuine super-telephoto reach for wildlife at moderate distances, sports, and nature photography. The Tele Auto designation indicates automatic aperture operation, and the Soligor branding represents lenses manufactured by various Japanese optical companies for the Allied Impex distribution network.
Build quality is functional with an all-metal barrel and adequate mechanical precision for the price point. The lens is more compact than might be expected at 400mm thanks to the slower f/6.3 aperture, and it handles adequately on Canon FD bodies with tripod support.
The Soligor 400mm f/6.3 is among the cheapest super-telephoto options available for Canon FD on the used market. While optical quality is basic, the 400mm reach provides genuine wildlife capability that no shorter lens can match.
