Sigma Launches DG Filter System
Sigma has launched a new line of multi-coated filters optimized for use on digital SLR cameras.
The product line consists of UV (clear) filters for reducing ultraviolet light as well as general protection, and circular polarizers in wide/thin and normal configurations. The wide/thin CPL line covers all standard Sigma lenses from 52-82mm front threads, with normal CPLs covering 86, 95 and 105mm front threads which match the larger telephoto lenses like the famed 50-500 and 120-300. UV filters are available in all the aforementioned threads.
