The worlds best range of independent lenses. Made to be fully compatible with all of the camera manufacturers bodies, Sigma offers a long list of lenses which includes the first stabilised system lens from an independent supplier. Many photographers would choose a Sigma lens instead of a camera manufacturers on a quality as well as on a price basis. Sigma lenses purchased from 1st September 2010 will now come with a 3 year warranty (if registered with Sigma UK within 30 days of purchase).
