Sigma has announced a new short-term offer for anyone who purchases a Sigma 10-20mm f/4-5.6 EX DC HSM ultra-wide angle lens. Buy the lens and you’ll be entitled to claim a free Sigma 77mm UV DG filter that’s worth over £60. This special promotion finishes on the 31st December 2012.

Protecting the front element of the lens from damage and scratches, Sigma’s DG filters benefit from a special multi-layer lens coating that has been developed to counteract the highly reflective characteristics of image sensors.
