Calumet 77mm UV SMC Filter

Available exclusively in ultraviolet, skylight and circular polarizers, Calumet's Super Multi-Coated Filters are a must with modern lenses or when lens hoods and compendiums cannot be used. These outstanding filters offer revolutionary performance in light transmission and color balance. Twelve layers of Super Multi-Coating are applied to the surfaces of the Skylight 1B and UV filters, which results in an average light transmission of 99.7%! Coupled with maximum surface precision, this allows increased resistance to flare, even at wide apertures. The Ultra-thin Circular Polarizing filters have seven layers of Multi-Coating applied to the rear surface to eliminate internal reflections and ghosting. Advanced thin selective film is used to guarantee perfectly polarized light with neutral color balance. Their slim 5mm profile avoids any vignetting and makes these filters ideal for use with wide-angle lenses.
