    Overview

    The FED-100 100mm f/6.3 is a tiny, slow lens in M39 mount, often overlooked but offering unique character. Sharpness is decent at f/6.3 or higher, though contrast and color may not be top-tier (Minolfan, djmike). Build is rare and collectible, with a special finder that is very hard to find. It suits users seeking a vintage look and collectors of FED accessories, but its slow speed and low contrast require careful shooting.
