Sigma Circular Polarising EX DG 49mm Filter

The technical details behind this filter
Ensure sharp images with the help of Sigma Circular Polarising EX DG 49mm Filter. This filter clears up haze in distant landscapes and delivers more saturated, vivid colours. It also helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The polarizing filters arrange, and filter directionally polarized light perpendicularly to the reflected light, permitting for the absorption of much of the light. The circular polarizers are perfect for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
