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. Simple to use, circular polarizing filters (such as Canon's PL-C) polarize light circularly, rather than linearly, so it does not interfere with autofocus or TTL light metering.

I use it on my Canon TS-E 24mm f/3.5L II lens. On a clear day with blue sky, it can darken the sky as it supposed to, and the results have more saturated blues. Its slim design also makes it suitable for wide angle lenses, though on a wide angle TS-E lens, the vignetting is inevitable, when it's shifted.
