UV protector; Circular polarizer 52mm Diameter 812 Color warming filter Protect your camera lens from ultraviolet light while boosting your artistic possibilities with the Tiffen Photo Essentials filter kit. The kit--which includes an ultraviolet filter, circular polarizer, and warming filter--is an ideal accessory for cameras with 52mm filter diameters. The ultraviolet filter prevents UV light from reaching the lens, helping increase clarity and reduce haze. As a result, your photos look crystal clear even in mountainous and coastal areas, where ultraviolet light is particularly strong. The circular polarizer, meanwhile, is essential for outdoor photography, as it deepens the intensity of blue skies and reduces or eliminates glare. (Note that the circular polarizer is designed expressly for autofocus cameras.) Finally, the kit offers an exclusive color-warming filter that improves the color of all skin tones. Ideal for portraits, the color-warming filter absorbs the blue cast often caused by electronic flashes or outdoor shade, adding warmth to pale, washed-out flesh tones. As a bonus, the kit includes a pouch for filter storage.
