Sigma 72mm UV filter advantages from Sigma's multi-layer lens coating, intended to counteract the extremely reflective characteristic of image sensors. With non-coated filters, the light would reflect off the image sensor, bounce off the lens and filter elements and re-enter the image sensor, producing a ghost image and disturbing the quality of the image.
To eliminate the ghost effect the Sigma 72mm UV is applied multi-layer coatings that dramatically diminish this effect. On the other hand, the resulting image is an optimum, neutral colour balanced. The 72mm EX DG UV Filter precisely removes the highly unwanted effect of ultraviolet light. Sigma ultra-violet is compatible with both colour and black-and-white film and digital sensors. It is the most effective filter for lens protection and general photography.
