Canon 52mm Circular Polarising Filter

Light rays which are reflected become polarised. Canon 52mm PL-C Circular Polarising filters are used to select which light rays enter your camera lens.

This filter removes unwanted reflections from non-metallic surfaces such as water or glass and also saturates colours to provide better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. The filter factor is between 2.3 and 2.8 (approx. +1.3 stops).

This Circular Polarising filter is specifically for the following IS (Image Stabiliser) Super Telephoto Lens Series: EF 300/2.8L IS USM, EF 400/2.8L IS USM, EF 500/4L IS USM and EF 600/4L IS USM. It can be rotated from the outside without removing it from the lens for precise control.
