Inca Pro 62mm Variable Neutral Density Filter

Operates on the same principle as a circular polarizing filter - rotate to the desired degree and shoot. Filter ring is indexed (lines) to mark the degree of neutral density you choose. Inca pro variable nd filters adjusts density, offering 2 to 8 stops of added density by easily rotating the outer filter ring. With excellent quality optical glass and precision processing, the inca pro variable nd filter will not produce unwanted colour cast. Suitable for use with super wide-angle lenses.
