Hoya Digital Filter Kit II 67mm Hoya Digital Filter Kit II includes: - x1 HMC UV(C) - a multi-purpose fine-weather filter - x1 Circular Polariser - a filter for colour and contrast enhancement - x1 NDx8 - a filter for wider apertures or longer exposures - x1 Filter pouch - x1 Filter guidebook The UV(C) filter cuts out UV rays to give astounding sharpness and clarity without the least affect on colour balance. Minimizes reflections on filter surface, reducing flare and ghosting. Engineered to enhance the performance of today's multi-coated lenses. Constant use for lens protection is recommended. The Circular Polarising filter allows you to select which light rays enter your camera lens. Removes unwanted reflections from non-metallic surfaces such as water, glass etc. Colours become more saturated and appear clearer, with better contrast. The ND (Neutral Density) filter (1) enables slow shutter speeds to be used, to record movement in subjects such as waterfalls, clouds, cars, seas etc.; (2) decreases depth of field by allowing wider apertures to be used, which helps separate subjects from their background; (3) decreases the effective ISO of high speed film (above ISO400) and allows it to be used outdoors in blight situations; and

allows cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.
