Singh-Ray 77 mm Vari N Duo
sku: SR77VNDDUO
Manufacturer Description
The Singh-Ray Vari N Duo filter allows you to adjust density from 2 to 8 f/stops, allowing you to greatly extend exposure times, or open up aperture to control depth of field more effectively. The built in polarization filter is easily controlled by rotating the ring just behind the ND Min/Max ring.
The LB Warming Polarizer reduces glare from sky, water, wet rocks, and other reflective surfaces.
