Sigma TC-1401 Tele-Converter 1.4x Canon

Attaching the Tele Converter TC-1401 between a telephoto lens and a camera increases the focal length by 1.4 times, while attaching the TC-2001 model doubles it. Both models feature SLD (Special Low Dispersion) glass elements that provide excellent image distortion correction. It is remarkable that one of the best glass materials is used for lens accessories. However, since Sigma aims for the best possible image quality, this is a logical development to meet the new "SGV" standards. The converters are dust and splash resistant, making them a durable construction for professional use. They are compact and lightweight, offering an easy way to extend the focal length range. Compatible with Sigma's Global Vision line of lenses (Contemporary, Sport, and Art).
