NISI FILTER UV PRO NANO HUC 40,5MM

Ultra-thin filters adopt a double sided, multi-coating lens technology that employs high quality Japanese ultraviolet absorption optical glass. It assures high transmittance and highly smooth surface that avoids unnecessary reflection. The frame is constructed from Brass using highly accurate brass milling and with thickness of only 3,5mm, which make this ultra thin filter to fit perfect even on super wide angle lenses to avoid vignetting.
