Zeikos 82mm Multi-Coated Circular Polarizer CPL Glass Filter w/ Rotating Mount For Sigma 10-20mm f/3.5 EX DC HSM, Sigma 12-24mm f/4.5-5.6 & Sigma 24-70mm f/2.8 Lens

Zeikos 82mm Multi Coated Circular Polarizing (CPL) Filter Polarizers provide color and contrast enhancement. Reflected light often shows up as whitish glare that washes out color in an image. A Polarizer corrects this problem producing deep, dramatically blue skies. It also removes glare from non-metallic surfaces, such as windows and water. Color saturation in general, especially outdoors, can be improved significantly. Think of it as sunglasses for your camera. Polarization rate of 99.9% for superb anti-reflection capabilities Multi-Coated technology significantly reducing lens flare and ghosting Ultra slim rim profile to avoid vignetting on wide angle lenses, while maintaining rotation Ideal for colour enhancement and contrast while maintaining overall colour balance
