Hoya HD Antistatic CIR-PL circular polarization filter

Hoya HD Antistatic CIR-PL Polarizing Filter

A polarizing filter changes the tones of an image visibly but naturally: the sky deepens, reflections are reduced, and colors become more saturated. Many landscape photographers keep a polarizer on their lens almost all the time, because it is really difficult to achieve the same result in image processing .

You can't get the detail lost under the reflection back into the image with the sliders, and the sky that has been darkened afterwards won't look the same. That's why a circular polarizing filter is the first filter purchase for many people after a regular protective filter.

Hoya HD Antistatic CIR-PL is part of Hoya's new HD Antistatic series. The glass is chemically strengthened optical glass. It has a 20-layer anti-reflective coating and a highly permeable polarizing film.

The series gets its name from its antistatic coating. Dust doesn't stick to the glass in the same way as a regular filter, and loose particles can be removed with a blower or a light wipe. In addition, the water and oil-repellent surface means fingerprints and water droplets can be removed with a microfiber cloth. The polarizer is turned and touched a lot when shooting, so a surface that stays clean easily is a big advantage in use.

• Removes reflections from water, glass and other non-metallic surfaces
• Deepens the blue of the sky and the green of vegetation
• Antistatic, water and oil repellent coating
• 20-layer multi-film coating and UV protection
• Lightweight rotating aluminum frame, sizes 49–82 mm

A polarizer is not just a sky filter. When the shiny surface reflection of leaves is removed, the natural green and autumn colors of vegetation come to the fore. In macro photography, the same phenomenon reduces bright reflections in a blurred background, making the background calmer and the subject stand out better.

The filter is available in sizes 49, 52, 55, 58, 62, 67, 72, 77 and 82mm.
