Sigma EX DG 82mm Multi-Coated UV Filter

Sigma EX DG 82mm Multi-Coated UV Filter

Designed for use with autofocus SLR cameras, the Sigma circular polarising filter cuts the glare from water and non-metallic surfaces, letting you enjoy crisper, clearer images. A circular polariser is intended to improve colour saturation and contrast, performing such tasks as darkening the sky in colour photography without affecting the colour balance. The filter's multi-layer coating optimises protection for the lens while further reducing reflection. The filter is of a very thin construction making it suitable for ultra-wide-angle lenses without causing vignetting.
