Canon 52mm Drop-in circular polarising filter II

Circular polarising filter for Canon super-telephoto lenses that drop into compatiable lenses to reduces the appearance of reflections and makes colours appear more saturated.

The PL-C 52WII 52mm Drop-In Circular Polarising Filter from Canon is designed for use with select super telephoto lenses that accept rear-mounted 52mm drop-in filters. The filter is rotated from a ring on the outside of the filter mount. You do not have to remove the filter to use it. The glass is secured within a strong metal frame that slips in and out of the rear mount with ease. The degree of polarisation can be seen through the viewfinder of your camera as you rotate the filter.

Circular polarisers help to reduce reflections and glare by filtering out light that has become polarised due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions.
