PRO1D C-PL allows you to remove unwanted reflection from nonmetallic surfaces such as water and glass. Kenko's CIRCULAR PL uses innovative polarizing material. And it makes Digital SLR camera's viewfinder image color difference has been corrected.
This medium-class filter series was developed in the mid-2000s when digital single-lens reflex cameras were popular. Adopting digital multi-coat technology, these filters achieve an overall filter transparency of 99% (protector) with a minimum price premium. The new-concept filter series employs a black-painted frame for reduced reflection in the glass, a knurled frame for easy attachment, and other user-friendly features. These filters function well not only with digital cameras but also with film cameras.
How to use PL-filters
PL filters achieve their greatest effect of eliminating glare when used at a 30-40 degree angle to a reflective surface (like glass or water). At midday when the sun is directly overhead, or at a 90 degree angle, the filter will have the least effect. These effects are easily visible by rotating the filter and looking through the viewfinder of the camera. Keep in mind that you will first need to adjust the polarizing filter before setting the exposure controls.
For deepening the color of the blue sky and making the clouds jump out at you, hold the camera at a right angle to the sun and take the photo when the sun is at a 30-40 degree angle in the sky.
When photographing distant subjects, scenery sometimes appears bluish. This is also caused by light polarization. Using the polarizing filter will help to greatly reduce the softness caused by atmospheric haze.
There are a variety of ways in which the use of polarizing filters can help you capture that perfect shot. Reducing the haze and enhancing colors may seem like simple effects, but once used, these effects will prove to be invaluable to photographers at any level of interest.

Black almite frame
Filters feature a black matte aluminum satin finish almite frame which reduces reflections.
Black rimmed glass
These filters are equipped with black rimmed glass to reduce the chance of light reflecting off the edge.
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.
UV protected case

General care and handling of the photographic filter
- Use filter carefully and always keep it clean. When cleaning use cleaning tissue or cleaning cloth. But before that remove as much dust and dirt as possible from the lens with a blower or brush.
- Avoid unnecessary cleaning of your filter.
- Filter is made of glass. When it is broken glass fragments may injure.
- Do not disassemble filter by yourself.
- When the filter is not attached to the lens, store it away from sharp objects. They may damage the filter glass.
- Keep filter away from children.
- Keep filters in plastic hard-sided case or filter pouch.
- Keep filters dry and away from direct sun light.
- Avoid storage in high humidity environment. Moisture drops due to the high humidity or dew on the filter can burn the coating and create traces on the glass surface that can be hardly wiped off.
