Cokin 52mm Nuances Vari ND2-400 filter, with Pouch Case 

The 52mm NUANCES Variable ND Filter from Cokin is a variable neutral density filter that is designed to mount onto lenses with 52mm front filter threads and provides an exposure reduction of 1 to 8 stops.

Its density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with dots and includes a rotation lever to further enable fast and precise positioning of the front ring.

This filter is constructed from Schott B270 glass for increased optical clarity as well as colour fidelity, and each glass surface features 16 layers of Cokin's EVERCLEAR 5 anti-reflection coating. These coatings are resistant to oil, dust, dirt, and scratches, offering greater protection to the filter and helping it to stay clean for longer than with uncoated filters. The coatings are also hydrophobic, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

• Variable neutral density filter allows you to apply differing amounts of density from scene to scene
• Darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required
• Provides an exposure reduction of 1 to 8 stops, allowing you to control depth of field and convey movement more easily
• Offers increased flexibility to use specific ISO settings or ISO films under bright ambient light
• Provides increased exposure flexibility while using cinema or video cameras within a designated film frame rate
• Constructed from Schott B270 glass for increased optical clarity and color fidelity
• 16-layer Cokin EVERCLEAR 5 multi-coating prevents internal ghosting and reflections; is oil, dust, dirt, as well as scratch resistant; and provides an improved beading effect with water for more efficient cleaning
• Slim, 9.5mm thick aluminium alloy filter ring assembly helps to prevent vignetting while remaining lightweight
• Side lever allows the filter glass to be easily rotated
• Front mount with 58mm front filter threads helps to reduce the likelihood of vignetting with wide-angle lenses
