    Overview

    The Canon R 35mm f/2.5 is a solidly built wide-angle lens from the early 1960s, designed for Canon Flex series cameras. Optically, it offers good sharpness at f/2.5 with some corner softness due to curvature of field at close distances, improving beyond 20 ft; best performance is at f/8. Weaknesses include susceptibility to mold and dust, and it is not recommended for use on certain later Canon bodies like the AE-1. It suits owners of Flex cameras or collectors, as modern FL/FD alternatives offer better image quality.
