Hoya Circular Polarizer Filter (HRT CIR-PL UV) – 62mm Polarizing Filter with UV Absorbing Glass, High-Rate Transparency Film for Camera Lens – Multi-Coated Aluminum Frame & Water Resistant

These filters offer both amateur and professional photographers HOYA's famous quality at reasonable prices. They have coatings applied to both surfaces to suppress reflection and increase light transmission. The HOYA HRT circular polarizer filter uses a newly developed High-Rate Transparency film that passes more visible light through the filter while still filtering the same amount of polarized light, this means it can transmit as much as 25% more light through the polarizing film giving the photographer about 1/3 stop more light than a standard circular polarizer. This new polarizing film is also used in the latest HD LCD TVs. The glass of the HOYA HRT filter also has UV absorbing properties making the HRT a combination UV & Circular Polarizing filter. The most common use for a circular polarizer filter is to darken bright blue skies in outdoor photography, but they can also reduce or eliminate reflections from non-metallic surfaces such as glass and water. By rotating the outer ring of the filter the change of effect can be seen by looking though the filter or through the viewfinder if it is mounted on a camera. HOYA is the world's largest optical glass manufacturer, producing glass to specification for almost every camera and lens manufacturer. HOYA is also the world's largest optical filter manufacturer.

• 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 62mm 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 62mm 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.
