H&Y Filters 77mm K-Series Variable Neutral Density and Circular Polarizer Filter Antlion Audio The Speed Rings are theThis 77mm K Series Variable Neutral Density and Circular Polarizer Filter from H&Y Filters is a filter that combines a solid variable neutral density element with a circular polarizer element. The variable neutral density element provides an exposure reduction of 1. 5 to 10 stops. Its 0. 45 to 3. 0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than would normally be required.
