The Hoya HMC 62mm PL-CIR is a precision circular polarizing filter engineered to enhance image quality by eliminating unwanted reflections and improving color saturation in professional photography and cinematography. Featuring Hoya's High Multi-Coating technology, this filter effectively reduces surface reflections, flare, and ghosting while achieving greater than 97% light transmission for exceptional contrast and color fidelity. The circular polarizing design is specifically engineered for autofocus SLR cameras and digital systems, allowing photographers to selectively filter polarized light by rotating the outer ring to achieve desired effects directly through the viewfinder.

This filter works by filtering out light that has become polarized due to reflection from non-metallic surfaces such as water, glass, and foliage. 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 and an increase in the saturation of skies and foliage.

The Hoya HMC PL-CIR is housed in a slim mount construction specifically designed to prevent vignetting when used with wide-angle lenses. The filter features a rotating front frame that allows photographers to adjust the polarization effect by simply turning the outer ring while observing the results through the viewfinder or LCD screen. The multi-coating also makes the filter easier to clean and more durable over time. The included protective lens case ensures the filter remains free from dust, scratches, and damage during storage and transport.
