Polarizing filters enhance picture quality by blocking harmful reflected light. Use it to reduce light reflections from glass and water surfaces or to improve color saturation. Simple to use, these filters polarize light circularly, rather than linearly, so they do not interfere with autofocus or TTL light metering. For use with lenses using rear-mounted drop-in filters, this polarizing filter can be rotated from the outside without removing the holder from the lens, enabling precise control. Filter fits select lenses with a 52mm diameter.
The Canon PL-C polarizing filter enhances picture quality by blocking harmful reflected light. Use it to reduce polarized light reflections from glass and water surfaces or to improve color saturation. These effects 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. Filter factor is between 2.3 and 2.8 (approximately 1.3 stops).
This 52mm drop-in circular polarizing filter is specifically for the following IS (image stabilizer) 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.
