A polarising filter will work with most camera systems and are not brand specific in any way. They range in price and quality from inexpensive entry level to professional-grade options. The defining factors include the amount of light which will enter the lens, which is referred to as light transmission, to the coatings on the filter which keep it clean and grease-free. The more light which enters the lens the better on the whole, as the shutter speed will be less affected. Polarisers will generally decrease light transmission by an EV stop down to two or three stops.
Rotating the filter whilst viewing the image through the LCD or viewfinder will demonstrate the effect in action. If used at the correct angle, blues skies will become bluer, reflections from wet leaves or rocks will disappear and the surface of water will become completely translucent rather than showing all manor of reflections. For these reasons landscape photographers in particular will always have at least one in their camera backpack.
It is always a good idea to keep your filters clean with a cleaning accessory and this stands true with CPL’s. A filter which has water spots, dust or other grime will sometimes degrade the final image, and can show as minor softening or blur in the photograph.
