Canon 58PLCII Polarising Filter

Polarising filters enhance picture quality by blocking harmful reflected light. Use it to reduce light reflections from glass and water surfaces or to improve colour saturation. Simple to use, these filters polarise light circularly, rather than linearly, so they do not interfere with autofocus or TTL light metering. For 58mm filter thread sizes, it still allows the lens cap to be attached to the lens to prevent damage to the filter if left attached when not in use.
