Product description
The Marumi 55mm CPL filter is a high-quality, Japanese-made circular polarizer designed to reduce reflections and enhance color saturation in photographs.
Product features
- Polarizing Effect: The primary function is to reduce reflections and glare from non-metallic surfaces like water or glass, and to increase color saturation and contrast, making blue skies deeper and foliage more vibrant.
- Optical Quality:Â It uses high-quality optical glass with a blackened outer rim to minimize internal reflections, flare, and ghosting.
- Multi-Coating:Â The filter has multiple layers of anti-reflective coating (e.g., 6 coatings in the Fit & Slim, up to 18 in the EXUS series) to maximize light transmission and minimize reflections off the camera’s sensor.
- Slim Frame:Â The filter features a thin, low-profile aluminum frame design (as low as 5mm high) to prevent vignetting, even when used with wide-angle lenses.
- Rotating Mount:Â The front frame rotates to allow the user to adjust the intensity of the polarization effect easily.
- Teflon-Coated Threads:Â The male threads of the filter ring are coated with Teflon to ensure smooth attachment and removal from the lens, helping to prevent jamming.
- Made in Japan:Â The filter is manufactured in Japan, which is often cited by reviewers as a sign of high quality and reliable construction.
