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 & filter elements & 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 & black-&-white film & digital sensors. Suitable for protective use & general photography. ...
