Sigma 72mm EX DG Digitally Optimised UV Wide
Angle MC Filter
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, 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 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.
