H&Y ND4 Magnetic Clip-on Filter for REVORING 58-77mm

Cross-polarisation is a physical phenomenon associated with VND filters. While some VND filters offer a smaller range of ND stops to avoid this, H&Y has chosen to retain the wide ND range of the REVORING with VND&CPL, allowing full coverage up to 10 stops for users of telephoto or medium telephoto lenses. 4 gradations (ND4, 8, 16, 400) are available for 3 REVORING sizes (46-62 mm, 58-77 mm and 67-82 mm).

This H&Y magnetic clip-on ND4 filter 58-77mm for RevoRing is compatible with select 58-77mm RevoRing filters and reduces exposure by 2 stops for finer image control. The added density can be used to extend the shutter speed for greater blur — for example, to smooth out water surfaces or emphasise motion. It can also be used to reduce depth of field and enhance background bokeh, helping to isolate the subject of a photo more effectively. In addition, it can help prevent the "X-pattern" that can occur when using a variable neutral density filter on a wide angle lens. By increasing the density and thereby widening the aperture, the X-pattern in the image can be reduced or eliminated.

This neutral density filter is made from 2 mm thick optical glass with a multi-layer coating for optimal light transmission, and a water-repellent coating that repels fingerprints, oil and water, making it easy to clean. The magnetic frame attaches easily to the RevoRing, and multiple filters can be stacked for a greater effect.
