Rotating ND filter ring with ND2 to ND400 range - The rotating ring provides variable light reduction from ND2 to ND400 without altering color balance, giving you versatile control over exposure. Enable slow shutter speeds on fast film or digital cameras - Use longer exposures to capture motion blur in waterfalls, flowing water, moving clouds, or other rapidly moving subjects. - Slim edge design prevents wide-angle vignetting, and the aerospace aluminum frame delivers durable performance. Durable, protected against the elements - An 8-layer MRC coating repels water and dust for easier cleaning and continued clarity. - The extra robust frame helps maintain durability and prevents jamming during use. Enhanced subject separation - By allowing a wider aperture, it helps reduce depth of field and separate the subject from the background for more emphasis and clarity. Use scenarios - Long exposure landscape: Capture silky water in a bright scene by using slow shutter speeds with the ND range. - Cloud movement in skies: Smooth cloud trails for dynamic, dramatic landscapes. - Bright daylight portraits or detail shots: Open the aperture further to achieve a shallower depth of field while controlling light, improving subject isolation.
