The new Tele Converter was developed exclusively for the new lens product lines. Attaching the Tele Converter TC-1401 between a telephoto lens and a camera increases the focal length by a factor of 1.4 and attaching the TC-2001 model by a factor of 2. Both models include SLD Special Low Dispersion glass elements that provide excellent image error correction. It is extraordinary that for lens accessories of good glass materials is used. However since Sigma strives for the best possible image quality this is logically the development to meet the new “SGV” standards. The converters are protected against dust and splash water making them a durable construction for professional use. They are compact and lightweight and offer an easy way to increase the focal length range.
