Sirui 77mm Ultra Slim S-Pro Nano MC Circular Polarizer Filter (Brass Filter Ring)

SKU #104893 MODEL #CPL77A

Overview

This 77mm Ultra Slim S-Pro Nano MC Circular Polarizer Filter from Sirui helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

Sirui Ultra Slim S-Pro Nano MC Circular Polarizer Filters are constructed from Schott B270 glass for increased optical clarity as well as color fidelity and provide over 99% transmission of visible light. This 77mm Ultra Slim S-Pro Nano MC Circular Polarizer Filter features a brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention.

Each glass surface of this 77mm Ultra Slim S-Pro Nano MC Circular Polarizer Filter is multi-coated to help eliminate internal ghosting and reflections. The filter is also coated for resistance to oil, static, dirt, and scratches, offering greater protection to the filter and helping it to stay clean for longer than with uncoated filters. The coatings are hydrophobic, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

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

Multi-coated to prevent internal ghosting and reflections.

Coated for oil, static, dirt, as well as scratch resistance and provides an improved beading effect with water for more efficient cleaning

Constructed from Schott B270 glass for increased optical clarity as well as color fidelity

Slim brass filter ring minimizes the potential for vignetting while enhancing durability and jamming prevention

Filter ring can be rotated to adjust the intensity of the polarization effect
