Sigma 77mm DG UV Filter

Sigma’s EX DG UV filters benefit from a 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. The Multi-Coated DG UV filter perfectly eliminates the harmful effect of ultraviolet light. The multi-coated UV filter can be used with both colour and black-and-white film and digital sensors. Suitable for protective use and general photography.
