Magic Filter 77mm diameter (single) for lenses with 77mm front filters The M77 is an original Magic filter designed to be mounted on the front of wide angle lenses with 77mm front filter threads, that do not have rear filter holders. Popular lenses that this filter is used with are Nikon 12-24mm, 17-35mm, 17-55mm, 18-35mm, Canon 10-22mm, 20-35mm, Sigma 10-20mm, Tokina 12-24mm and Tamron 11-18mm and 19-35mm. This filter measures approximately 75mm in diameter. This filter can also be used on other lenses with smaller filter threads. It can easily be cut down to size with our stencil and scissors to fit 52mm, 58mm, 62mm, 67mm and 72mm filter threads. This filter is designed to be mounted on the front of the lens, held in place behind a dioptre or clear glass filter. As this filter is made from the original Magic formula the photographer must set the white balance manually (using preset, custom or manual WB) every time they change depth by a few metres during the dive. This is easy to do and takes just a few seconds on most modern digital cameras. This filter is designed specifically to work with the white balance of a modern digital camera in blue to blue-green waters. Magic filters are designed for available light underwater photography. The original Magic works from the surface down to 15m (50ft), although many users are very happy with the results of this filter down to 20m (65ft). All filters are optical quality polyester gels, manufactured for Magic Filters to their own recipes, by one of the world's leading filter companies. All Magic filters are supplied with detailed instructions. Sample photo with the M77 and 12-24mm lens
