Product Description & Reviews
Digitally Optimised (DG) Filters EX DG filters benefit from Sigma's multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens and filter elements and re-enter the image sensor, creating a ghost image. The multi-layer coating dramatically reduces this effect. In addition to this, an optimum, neutral colour balance is ensured, increasing the white balance accuracy of the digital camera. Wide Multi-Coated Circular PL It reduces the glare and reflections from glass and water and other non-metallic surfaces. It deepens blue skies, and saturates the colors. The Sigma circular PL filter is designed to give best performance with AF Cameras. You can monitor the changes at different angles through the viewfinder as you rotate this filter. Remove unwanted reflections from nonmetallic surfaces such as water or glass with the Sigma AFL-950 46mm polarizing filter. Polarizing filters are used to determine which light rays enter your camera lens. By rotating the filter--viewable through the viewfinder--and changing its orientation to the sun, you can achieve a variety of different light effects, including saturating the colors, removing haze from outdoor shots, or removing reflections, all without affecting the overall color balance. Note: Circular polarizer?s are specifically designed for use with auto-focus SLR cameras, but they'll also work on manual systems and video cameras without problems.
