The Hoya 27mm Introductory Filter Kit is a general purpose starter kit.
Ultraviolet (UV) Filter
Hoya Haze (UV) Filters are wise investments. They help protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs.
Circular Polarizing Filter
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
Warming Filter (Intensifier)
The Hoya Warming filter controls the bluish coloration that affects daylight film. They can also remove excessive blue from the effects of electronic flash. Reduces blue to green color and makes the color of human skin look more sun-tanned. Combination with Pro 1UV filter is recommended for outdoor shooting.
Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras).
