Marumi Variable ND2.5-ND500 Filters

Marumi's Variable ND filter gives you adjustable light reduction from ND2.5 to ND500 in a single screw-in filter. It is a versatile tool for landscape, coastal and portrait photographers who want slower shutter speeds or wider apertures in bright light.

Rotate the filter to dial in the density you need without shifting colour balance, creating silky water, smooth skies or shallow depth of field in full sun. Despite its double-frame construction the mount is ultra-thin, keeping vignetting to a minimum.
