The H&Y RevoRing Black Mist 1/4 Filter is a versatile camera accessory designed for multiple lenses with diameters ranging from 46 mm to 62 mm using a single unit. This innovative filter system features retractable blades that securely mount to lenses with various thread sizes, eliminating the need for multiple filters or step-up rings. The Black Mist Filter with 1/4 density creates a cinematic aesthetic by softening hard edges, diffusing highlights, and reducing skin imperfections in both photography and videography. The filter system is available in three density levels - 1/8, 1/4, and 1/2 - allowing photographers and videographers to achieve different degrees of diffusion. Additionally, the RevoRing platform supports the magnetic attachment of complementary filters, including variable neutral density and circular polarizers. Crafted with precision engineering, the filter maintains optical quality and provides consistent diffusion properties across the entire image field. The Black Mist effect expands creative possibilities by adding an atmospheric quality to images without compromising sharpness or color accuracy. This universal mounting system offers a practical solution for photographers working with multiple lenses of varying diameters, as it reduces equipment load and simplifies filter management during shoots. Its robust construction ensures reliable performance under various shooting conditions while remaining compatible with standard lens protection practices.
