K&F 52mm Ultra-Low Reflection Variable ND Lens Filter, ND2-400 K&F Concept

Podrobný popis

variable ND filter 52 mm, changes the amount of light steplessly as you turn it.

• Screws onto a lens with a 52 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.
