The Canon PLC-B is a circular polarisng filter that can be used with all interchangeable lenses for Canon SLR cameras. Using the Circular Polarising Filter PLC-B enables you to block out reflections from surfaces such as water and shop windows, resulting in clear, glare-free images.
As well as blocking surface reflections, the filter will also deepen and intensify the blue of the sky on a sunny day. You will see this effect most clearly when your shooting angle is at right angles to the sun’s rays.
This filter has a front thread. Lens caps can be attached to the front of the filter.
