Haida NanoPro MC Circular Polarizer Filter 49mm

The Haida 49mm NanoPro MC Circular Polarizer Filter is designed to minimize reflections and glare by filtering out polarized light caused by reflections on non-metallic surfaces. Sunlight becomes partially polarized when it reflects off electrons in air molecules, scattering the light and creating a hazy appearance. This polarizing filter works by aligning and blocking this polarized light, allowing it to pass perpendicularly to the reflected light. As a result, it significantly reduces glare and reflections while enhancing the saturation and vibrancy of skies and greenery.

• 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.
• 2.5x filter factor reduces exposure by 1.3 stops.
• Multicoated to prevent internal ghosting and reflections.
• Aluminum-alloy filter ring for durability while remaining lightweight.
• Filter ring can be rotated to adjust the intensity of the polarization effect.
• 49mm front filter threads allow for use with other filters.
• Side knurlings to provide a more textured grip when mounting or removing it from a lens. Constructed from optical glass for clarity.
• Plastic filter case for storage and transport.
