A Circular Polarising filter enhances picture quality by blocking harmful reflected light. Use it to reduce polarised light reflections from glass and water surfaces or to improve color saturation. Simple to use, circular polarising filters (such as Canon's PL-C) polarise light circularly, rather than linearly, so it does not interfere with autofocus or TTL light metering.
This drop-in style rear filter is designed to work with Canon Telephoto and Super Telephoto lenses that have a rear filter mount.
Compatible with the following Canon lenses:
