Sigma filters

The Sigma EX DG filter series are very thin to avoid any vignetting when used with wide angle lenses and feature high quality multi-layer lens coating in order to protect the image sensor and reduce a ghost effect. Additionally, an optimum neutral colour balance is ensured, increasing the white balance accuracy of the digital camera. The Sigma multi-coated protective UV filters can be used with both colour and black-and-white film and digital sensors to eliminate the harmful effect of ultraviolet light. They also serve as an extra permanent protection of your equipment for all types of photography. While the Sigma circular polarizing filter series deepen the intensity of blue skies and increases colour saturation, eliminate glare and reduces the reflection. The Sigma  EX DG filters are a perfect match to accompany Sigma lenses.
