H&Y RevoRing 37-49mm Variable ND3-ND1000 and Circular Polariser Filter

The H&Y RevoRing is an innovative, dual-function filter system designed for photographers and videographers seeking creative control over light and reflections. It combines a variable neutral density (VND) filter with a circular polariser (CPL) in a single, integrated unit, eliminating the need to stack multiple filters on your lens. This all-in-one solution allows for smooth adjustment of light transmission from ND3 to ND1000 (1 to 10 stops) while simultaneously managing glare and enhancing colour saturation through its rotating polarising element. The filter features a unique, reversible mounting ring system that accommodates lens threads from 37mm to 49mm, providing versatile compatibility with a range of prime and zoom lenses. Constructed with high-quality, multi-coated optical glass, it is designed to maintain image sharpness, minimise colour cast, and reduce flare. The slim-profile design helps prevent vignetting on wide-angle lenses, and the smooth rotation mechanism allows for precise adjustment of both density and polarisation during shooting. This filter is ideally suited for landscape, portrait, and travel photographers, as well as videographers, who require flexible exposure control in changing light conditions. It enables the use of wider apertures for shallow depth of field in bright sunlight or longer shutter speeds for creative motion blur effects, all while cutting through unwanted reflections from water, glass, or foliage. Its practical, two-in-one design simplifies kit management and offers significant creative potential for enthusiasts and professionals alike.
