K&F 77MM ND4-ND64 (2-6 Stop) Variable ND Filter and CPL Circular Polarizing Filter 2 in 1 with 28 La K&F Concept

Podrobný popis

Nano-X — variable ND filter 77 mm, changes the amount of light steplessly as you turn it.

• 28 anti-reflective layers
• Screws onto a lens with a 77 mm thread.

A variable ND replaces a whole set of fixed grey filters — turning the front ring changes how much light gets through, steplessly. While filming the shutter stays at 1/50 s even as the sun goes behind a cloud and comes back, with no need to stop the take or swap a filter.

Two functions in one piece of glass: the variable ND cuts two to six stops and the polarising layer also takes the glare off water and glass. One filter sits on the lens instead of two stacked, so there are no extra reflective surfaces and no added risk of dark corners.
