77mm True Match Variable Neutral Density Filter Kit
This is a Schneider True-Match Variable Neutral Density Filter. The 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 carefully matched set of filters work 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.
