Used to filter out haze at minimize unwanted glass, and water reflections. These filters enable the lens to capture clear shots with rich color texture even in bright lighting conditions. It allows polarization control for color saturation as well as better contrast. The optical glass measures 2.4mm with 0.3 optical density and clarity of 50% reflection reduction. Okko Lite CPL is optimized with improved tonal and color saturation as well as AGC Japanese optical glass to absorb UV light which results to minimal ghosting and less haze all throughout the lens. These filters are available in sizes 37mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, and 82mm. Product Features in Detail Rich, clear shots - Filter out unwanted reflection from water, snow or glass and eliminate haze for crisper images. Capture rich, clear shots in challenging bright conditions. Color saturation and greater contrast - This affordable, adjustable filter allows you to control polarization for color saturation and greater contrast. Featuring a glass thickness of 2.4mm and an optical density of 0.3. Reduced polarization through Japanese AGC optical glass - Okko Lite CPL filters reduce haze, allowing you to achieve greater color and tonal saturation for clearer images with better contrast. Aluminium alloy frame - Constructed from high quality, light weight matte black aluminium and designed to work with all standard lens caps. Thin frame to minimise vignetting - Thin frame minimizes the vignetting effect when shooting wide open.
