HOYA, the world renowned optical glass manufacturer, presents an innovative high definition line of filters..

Light rays which are reflected by any surface can become polarized so polarizing filters are used to select which light rays enter your camera lens. CIRCULAR PL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarizing filters do not affect the overall color balance of a shot.

Reduce Glare and Reflections with the CIRCULAR PL
Using the CIRCULAR PL filter, reflections and glare can be reduced significantly from non-metallic surfaces. A camera angle of 30 degrees from the reflecting surface (glass, water, etc.) is ideal for maximum effect.

Attach or Retouch?
Wouldn’t you rather spend your time attaching the right filter than retouching every photo? Attaching the right filter can replace the need to retouch each digital photo you take.Using filters allows you to spend more time taking photos and less time in front of the computer!

HARDENED GLASS
Hardened optical glass that has 4 times the breaking strength in ANSI standardized testing (ANSI Z80.3 : 2001) where a steel balls of varying size and weight were dropped from a height of 50 inches onto the glass.

HIGH TRANSPARENCY POLARIZING FILM

The polarizing film is the same as that used in the latest high 
definition LCD TV screens. It has 25% higher light transmission than standard polarizing film used in current photographic filters.

WATERPROOF / SCRATCH & STAIN RESISTANT MULTI-COATING
Specialized coatings that are not just water-proof to repel water spots but also hardened to be scratch and stain resistant. Of course these coatings are from HOYA so they are greatly reduce reflections off the surface of the glass allowing you to capture more light in your photos. 

BLACK ALMITE FRAME
Filters feature a black matte aluminum satin finish almite frame which reduces reflections.

LOW PROFILE FRAME
Ultra thin filter frames to help avoid vignetting on super wide angle lenses are also designed to hold a lens cap.

KNURLING EDGE FRAME
These filters are equipped with a straight knurling edge for non-slip, easy attachment and removal.
