- Coating: Multi-Coated
- Material: Optical Glass
- Light Transmission: High-Rate Transparency (HRT) Film Technology
- UV Protection: Yes
- UPC: 024066051691
Key Features
DUAL-FUNCTION DESIGN WITH CPL + UV FILTERING – Combines circular polarizer and UV lens filter in one unit to reduce reflections and absorb ultraviolet light; enhances image clarity and contrast with minimal haze in all lighting conditions.
HIGH-RATE TRANSPARENCY FILM TRANSMITS MORE LIGHT – Uses advanced polarizing film that allows up to 25% more visible light through the camera filter, offering 1/3 stop more light than standard circular polarizer lens filters for improved exposure control.
ROTATABLE FRONT RING FOR POLARIZATION ADJUSTMENT – Our 77mm lens filter features a smooth-turning outer frame to control the degree of polarization; effectively manages glare and reflections from water, glass, and other non-metallic surfaces.
SLIM, LIGHTWEIGHT ALUMINUM FRAME REDUCES VIGNETTING – Constructed with a low-profile frame that minimizes vignetting on wide-angle lenses; durable and lightweight build supports consistent performance on 77mm cpl filter threads.
MULTI-COATED OPTICAL GLASS WITH UV ABSORPTION – Hoya circular polarizing filter features multi-coated glass for reduced surface reflections and accurate light transmission; black-rimmed edges and water-resistant construction enhance durability and image purity.

Pros & Cons
👍 Pros
- Dual-function design integrates both circular polarizer (CPL) and UV filtering in one unit, reducing reflections and absorbing UV light.
- Utilizes High-Rate Transparency (HRT) film, transmitting up to 25% more visible light than standard CPLs, offering 1/3 stop more light for better exposure control.
- Features a rotatable front ring for precise adjustment of polarization, effectively managing glare from water, glass, and non-metallic surfaces.
- Constructed with a slim, lightweight aluminum frame that minimizes vignetting, especially beneficial for wide-angle lenses.
- Equipped with multi-coated optical glass and water-resistant construction, enhancing durability and ensuring accurate light transmission while reducing surface reflections.
👎 Cons
- The 77mm filter size is specific and will only fit lenses with matching filter threads, requiring adapters for other sizes.
- While combining two functions, it is still a single-purpose accessory that does not add any optical magnification or focal length adjustment.
- The HRT film, while efficient, may still introduce a slight color cast that requires minor post-processing correction in certain shooting conditions.
- The effectiveness of the polarizer depends on the angle of the sun, making it less effective in certain lighting or shooting directions.
- Maintaining the cleanliness of a multi-coated filter is important, and smudges or dust can be more noticeable due to its light transmission properties.
Frequently Asked Questions
What are the dual functions of the Hoya Y7POLC077 filter?
The Hoya Y7POLC077 filter combines both circular polarizer (CPL) and UV filtering capabilities, reducing reflections and absorbing ultraviolet light in one unit.
