B&W Filters: Worthy of the Finest Lenses B&W filters are manufactured in the style of the best optical lenses. Each filter is cut from raw cylinders of pure Schott/ Mainz optical glass, the same glass used by the world's top lens manufacturers. The filter mounts are made from black anodized solid brass. These high-quality components, combined with B&W's modern production technology & rigorous quality control, produce the flattest possible filters. This precision flatness (plano-parallelism) & B&W's high-quality anti-reflection coating, which is applied to both sides of the filter, minimizes the possibility of image deterioration due to flare. ...

Calumet 77mm ND2X Neutral Density MC Filter Calumet's Multi-Coated filters are a must for modern digital stills & camcorder lenses, particularly where lens hoods or compendium shades cannot be used. These outstanding filters offer revolutionary performance in light transmission, colour balance & flare control. Calumet Multi-Coated Filters minimise flare & ghost imaging in situations where unwanted light falls on the filters surface. The result is an average light transmission of over 97%, producing sharp contrast & well-balanced colour. Multi-Coated filters are available in a wide range of filter types & are highly recommended for maximising the performance inherent in multi-coated lenses. ND2X Neutral Density: Eliminates overly bright, washed out images by reducing the amount of light entering the lens without affecting colour rendition. Balances exposure & controls depth of field. 2X density = 1 f-stop. Can be combined to enhance effect. ...

A clear (colorless) filter for color as well as black & white use. Also serves as a permanent lens protector. Multi-coated to minimize reflection at the filter surfaces which reduces flare & ghosting. ...

Hoya’s range of PRO-ND Neutral Density filters utilises their new metallic ACCU-ND technology to yield a truly neutral colour balance. The Hoya PRO-ND range is aimed at the still photography & HDSLR video markets & provides a range of 9 filters from two-stop to ten-stop light reduction. Hoya’s meticulous use of optical glass & ACCU-ND coating on both surfaces ensures no colour shift as you move from one density to the next
- a common problem with other brands of neutral density filters. ND filters reduce the amount of light entering your camera lens & allow wider apertures & slower shutter speeds for creative & dramatic effect, even in bright lighting conditions.
