    Overview

    The Canon FD 400mm f/4.5 is a manual focus lens suited for animals, sports, and portraiture when the subject is centrally framed and surrounded by green, as it is well corrected for green colors (stevemark). However, lateral chromatic aberrations can be significant in other scenes, such as landscapes (stevemark). Build and handling are not discussed in detail, but the lens is described as 'not a terrible lens' if used appropriately (Blazer0ne, chhayanat). It best serves photographers who can work within its optical limitations.
