Hitech's 67mm 0.9 Blender Camera Filter produces a grey neutral tone and is used in photography to reduce light, enabling more control over exposure and depth of field without affecting color contrast. This filter is a neutral density blender filter. A blender is the same as a graduated filter, but with the transition taking place gradually over the whole length of the filter rather than in the middle.
67mm is specifically designed for smaller consumer DSLR lenses and mirrorless cameras
Fits the Formatt-Hitech 67mm and Cokin A Series holder systems, so a single filter is usable on multiple lenses
Made from the highest quality optical resin available, with an index of refraction nearly identical to the finest optical glass
High scratch resistance, low material fatigue, and chamfered corners to resist breakage so the filter will provide years of service
