Sigma Ex Circular Polarizer (CPL) Lens Filter 52mm
Digitally Optimised (DG) Filters
This Sigma Ex Circular Polarizer Filter is coated to repel water drops and resist smudging from fingerprints. It is also treated to exhibit antistatic properties to prevent microscopic dust from clinging to the front surface. This helps to ensure sharp images.
- Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
- Polarizing filters arrange, and filter directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light
- Clears up haze in distant landscapes and provides more saturated, vivid colors
- Strongest effect when used at a 90° angle from the sun
- Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features
- Constructed from water, oil, and static resistant glass
