Schneider 77mm True Match Variable Netural Density ND 0.45 to ND 3.45 MKII Filter, 1.5 to 11.5-Stops

New Vari-ND Filter Slimmer, Lighter and More Neutral
The True-Match Vari-ND MKII filter is Schneider Optics' most neutral variable ND filter to date and features 1.5 to 11.5 stops of light control. The True-Match Vari-ND MKII filters each feature low profiles, smooth rotating rings, and clear marks for choosing strengths while shooting. The effect is achieved by stacking highly neutral gray polarizing filters within a filter cell and rotating them to block the desired amount of light.Despite its double-frame structure, the Schneider Vari-ND MKII employs a slim 5.9mm profile to limit vignetting. The True-Match Vari-ND MKII, with 10 stops of light blocking power, eliminates the need for purchasing and stacking multiple ND filters.

Neutral Density (ND) Filters control exposure or depth of field under various lighting conditions without affecting color or contrast. ND filters are used if too much light restricts creative possibilities. They reduce the light in accordance with their density. They, therefore, allow more widely opened apertures. For very bright situations the aperture would also have to be closed. This would mean losing the option of a short depth of field.

Neutral Density
• Control exposure or depth-of-field under various lighting conditions
• Diminish distracting backgrounds by allowing the use of wider aperture
• Helps control the amount of light reaching the sensor or film without depending only on the lens aperture
• Enable even exposure in unbalanced lighting conditions
