The PROMASTER Digital HGX Protection filter is a crystal clear colorless filter with second generation advanced anti–reflective coatings designed especially for use with digital imaging sensors. There is no filter factor and it's primary purpose is to protect your valuable lens surfaces.
The PROMASTER Digital HGX UV filter absorbs the ultraviolet rays which often makes outdoor photographs hazy and indistinct. It is a multi-purpose fine-weather filter for color as well as black and white photos and also serves as a permanent lens protector.
Light rays which are reflected by any surface become polarized. Polarizing filters are used to select which light rays enter your camera lens. The Digital HGX Circular Polarizing filter allows you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. It also will enable colors to become more saturated and appear clearer, with better contrast.
The Professional Lens Cap is MORE than your everyday lens cap. ProMaster Lens Caps are precision molded for optimum fit and use a center activated locking system that aids in the secure fit of the cap.
