Collector Notes:
This lens is part of Fuji’s lesser-known but optically respected lineup from the 1970s–80s. Versions may include EBC coating (if marked), and some were rebadged or rebarreled for third-party distribution. The f/1.6 aperture is rare and offers a unique rendering—soft wide open, sharp when stopped down. Minor fungus may slightly reduce contrast in backlit scenes but is unlikely to impact general use. A great candidate for restoration or creative vintage shooting.
