Sigma 1.4x TC-1401 Teleconverter - Canon Fit
The Sigma 1.4x TC-1401 teleconverter has been developed exclusively for Sigma's Global Vision lenses, such as the Art, Sports and Contemporary range. By mounting it in between a telephoto lens and a camera, the offered magnification of focal length is 1.4x. The Special Low Dispersion glass elements offer aberration correction, while the dust-proof and splash-proof construction increases its longevity. The TC-1401 offers full communication between the lens and camera and will support autofocus at F8.
