Hoya 40.5mm Digital Filter Kit with 3 Filters & Pouch
UV (C) Filter Information A must for every lens! This UV (C) lens filter absorbs the ultraviolet rays, which often makes outdoor photographs hazy and indistinct. Also serves to protect the lens from scratching, dirt, and dust. Plus, this UV filter DOES NOT cut down (97% effective transmission) on light coming into the lens unlike non coated filters. All new 4mm slim frame is compatible with wide-angle lenses and is double-threaded, which allows use of regular snap-on lens caps or allows other filters to be stacked on top. Made in the Philippines. Circular Polarizer Filter Information Light rays which are reflected by any surface become polarized and polarizing filters are used to select which light rays enter your camera lens. Cir-Polarizing (Circular Polarizing) filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable 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. HOYA's polarizing filters do not affect the overall color balance of a shot. This standard circular polarizer is un-coated has a 7mm thick frame and is made in the Philippines. NDx8 Filter Information Neutral Density (ND) filters help reduce the amount of light entering the lens, but have no affect on color balance. The ND 8 filter has a filter factor of 3-stops, so you are able to slow down the shutter speed or increase the aperture by 3-stops. This standard NDx8 filter is un-coated has a 5mm thick frame and is made in the Philippines. The main uses are: 1. To enable slower shutter speeds so as to emphasize movement, such as waterfalls, clouds, the sea, automobiles, etc. 2. To enable wider apertures to be used so as to decrease the depth of field, which is very desirable in portraiture or macro work.
