Haida’s latest line, Red Diamond filters, promises all the advantages of  the Nanopro filters and are engineered to be the toughest line of  filters in Haida's current offerings. The Red Diamond filters feature a  shock-and-scratch-resistant design, making them ideally suited to the  harsh challenges of outdoor landscape photography.

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.

An ND Filter provides a solid stop exposure, creating a darkening of the  entire image and allowing you to photograph with a wider aperture and  slower shutter speed. By slowing your exposure time or increasing your  aperture, you are able to control depth of field and convey movement  more easily. Neutral Density filters do not affect the overall  coloration of the image.
