Bower - 77mm Variable Neutral Density Lens Filter

The Variable Neutral Density Filter, compatible with all analog and digital camera lenses with the popular 77mm filter size, gives you the ability to use fast film in bright outdoor conditions. ND, or neutral density, filters allow you to do a number of things that would otherwise be impossible. By reducing the amount of light, you can record movement in subjects such as waterfalls, clouds, cars and more. You can also drop your aperture to allow a wider focus, helping separate subjects from their background. This filter offers a range of up to eight stops of light. Compatible with lenses with 77mm filter threads including: Canon 17-40mm, 10-22mm, 17-55mm, 24-105mm, 70-200mm f/2.8, 24mm, Nikon 10-24mm, 12-24mm, 17-55mm, 16-35mm, 24-70mm, 24-120mm, 24mm f/1.4, 28-300mm and Pentax 16-50mm f/2.8 lenses.
