Engineered in Japan by Fuji Photo Film Co., it features a stunning 180-degree diagonal field of view with characteristic fisheye perspective curvature and outstanding optical sharpness. Fitted with a built-in rotating internal filter wheel (featuring UV, Skylight, Yellow, Orange, and Red filters), it allows instant tonal control without needing external front filter threads. Built with heavy-duty, all-metal precision construction, this lens was professionally serviced in September 2026. It comes complete with its original front lens cap, rear cap, and protective hard leather case—ideal for vintage 35mm film SLRs or for adapting to modern digital mirrorless systems.\u003c\/div\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\u003cb\u003eCondition\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003eOverall Condition: Excellent\u003c\/div\u003e\n\u003cdiv\u003eOptics are fungus and haze free with possible minor dust.
