K&F 86mm ND2-32 (1-5 Stop) Variable ND Filter and CPL Circular Polarizing Filter 2 in 1

Nano-X — variable ND filter 86 mm, changes the amount of light steplessly as you turn it.

• Screws onto a lens with an 86 mm thread.
• The surface repels water and grease and resists scratches

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.

The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field.

The filter combines two pieces of glass that otherwise have to be stacked: a polariser and a variable ND from ND2 to ND32. That removes one element from the light path and with it the vignetting risk of two stacked filters. The frame carries five marks from ND2 to ND32, so the strength can be set blind, and the knurled rim grips even in gloves.
