Haida Red Diamond Filters feature an ultra-thin Nano Multicoating that retains superb image sharpness as well as delivering true color with zero color cast. The Red Diamond series is double the strength of a normal glass filter, which provides for a low risk of accidental breakage. With a waterproof, oil and fingerprint proof Nanopro coated surface, this filter is easy to clean and ideal for use in harsh environments due to its scratch resistance. Quality and convenience come together with the R5 rounded corner design making insertion into the Filter holder much easier.
Hard Edge Graduated Neutral Density Filters start clear at the bottom of the filter before transitioning quickly into the Neutral Density effect as it approaches the center and then becoming strongest at the top of the filter. These filters are rectangular in shape (150x170mm) to provide more flexibility to move the filter up or down within the holder to precisely position the graduation line, for ultimate create control.
Haida filters ship in a protective metal case and are 2mm thick so they are compatible with many of the most popular 150mm filter holders available today, including the Haida 150mm M15 Filter Holder and the LEE SW150 Filter Holder.
