CIR-PL UV FILTER

The perfect filter to capture seasons

High-Rate Transparency Film

This 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. The HOYA HRT circular polarizer

filter transmits 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.

UV Absorbing

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 also can 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.
