The Schneider 77mm True-match Vari-ND Thread-in Filter is a perfect choice for DSLR cameras with high ISO settings. It allows the user to select the lens f/stop and camera speed independent of ambient light conditions. This filter works by taking two carefully matched filters and stacking them in combination to produce a density range from 1-1/3 stop loss to 11 stops of light loss.
By selecting the best quality materials, Schneider variable ND offer 11stops (ND3.3) attenuation with no blue color shift at maximum density which is a common problem with inferior and unmatched materials common in lesser variable ND filters. The 77mm True-Match Vari-ND Thread-In is a single low profile filter with both True-Match Polarizing filters in the correct orientation for maximum ease of use and efficiency. The low profile ring prevents vignetting on most DSLR and Video Camera lenses. Simply turn the built in rotating ring to dial in the perfect amount of ND for your scene. Step rings are available in common sizes to adapt the 77mm size to smaller lens thread diameters.
