Sigma's TC-1401 1.4x Teleconverter
increases the focal length of select Canon EF-Mount Global Vision
lenses by a factor just short of one and a half. The TC-1401 fully
integrates camera and lens, and permits autofocus at aperture settings
up to f/8. The splashproof and dustproof teleconverter includes a
Special Low Dispersion (SLD) element, which limits chromatic
aberrations and contributes to overall image quality. The attachment of
the TC-2001 will cause light loss of approximately one stop. Includes
soft zippered case.
