This group includes everyday filters which can be left on your lenses, such as Skylight 1B, UV and Polarizing. These are the first filters that every photographer should ensure they own. Skylight and UV filters should be constantly fitted to a lens to give improved clarity and color balance as well as offering protection to your lens. Polarizing filters have several uses such as eliminating unwanted reflections, increasing color saturation and enhancing contrast. As to whether you should use Circular Polarizing or Linear Polarizing filters with your camera, we recommend that you refer to the detailed explanation later in this catalog.
