Fotodiox Pro 145mm Ultra Slim Neutral Density 4 (2-Stop) Filter - Pro1 Ultra Slim Multi-Coated ND4 Filter (Works with WonderPana 145 & 66 Systems)

Foodoir Pro 145mm MC-ND4 Ultra-Slim Filter is a true neutral density filter designed to darken the image by 2 stops. The filter features an even, neutral gray color for creative photography applications. MC-ND4 Ultra-Slim filter offers a 2-stop EV value which allows you to slow down the shutter speed or use a larger aperture in bright light conditions. Neutral Density filters have their unique applications and offer the possibility of achieving otherwise impossible results. ND filters reduces the amount of light reaching the film/CCD. The filter is single threaded and much thinner than a standard filter to minimize any possibility of vignette when used with WonderPana Classic and WonderPana Free Arc 145mm filter holders. The lens is multi coated to correct for color balance as well as minimize reflection at the filters surface; therefore, reducing flare and ghosting. Foodoir ND filters are neutral grey and do not color cast the images.
