The technical details behind this filter ProMaster Circular Polariser Standard 40.5mm Filter allows you to remove unwanted reflections from non-metallic surfaces such as water, glass, etc. This filter also enables colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. ProMaster polarizers do not affect the overall color balance of a shot. It is important that you choose the correct version of ProMaster Polarizer for your camera. Many of today's cameras use semi-silvered mirrors or prisms to split the light entering the viewfinder to calculate exposure and focusing distance. Polarizing filters can sometimes interact with these items to give unpredictable exposure or focusing. So, we recommend that you choose a circular polarizer unless you have a manual focus camera that has no beam splitter. If you will be using your Polarizing filter on a lens that has a focal length of 28mm or wider, we recommend that you use a Wide Circular Polarizer to avoid a possible vignette effect.
