OVERVIEW
Canon's 77mm Circular Polarizing Filter is useful for reducing reflections and glare while improving overall color and tonal saturation. This filter helps to produce a noticeable increase in saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions, by filtering out light that has become polarized due to reflection from a non-metallic surface. A circular polarizer varies from a linear polarizer in that it allows for full use of the autofocus and auto-exposure capabilities of a camera.

Should I use step-up rings or buy separate circular polarizers for lenses with different filter sizes?
