72mm - Hoya 72mm UV(0) Pro1 Super HMC Filter
New technology has enabled HOYA to produce superior performance Skylight and UV glass in just 1mm in thickness, which is tempered for increased strength. The glass is mounted in a super slim 3mm ring (with front filter thread), which avoids vignetting and results in a 40% weight saving over standard models. Twelve layers of super multicoating are applied to the surfaces to produce an average light transmission of 99.7%! NO LONGER AVAILABLE.
