Canon EF Mount. We carry this teleconverter in multiple mounts with this one being the Canon version.
Compatible with Global Vision Lenses. At this time, the TC-1401 is only compatible with the Sigma 120-300mm f/2.8 DG OS HSM A1, Sigma 150-600mm f/5-6.3 DG OS HSM Sports A1, Sigma 150-600mm f/5-6.3 DG OS HSM C A1, and Sigma 500mm f/4 DG OS HSM Sports.
1.4x Magnification. When mounted to a compatible lens, this teleconverter increases the focal length by 1.4×. Do note this causes approximately one stop of light loss.
High-Quality Optics. The five-group/seven-element optical formula includes one Special Low-Dispersion element to help eliminate chromatic aberrations and produce high-quality images with minimal degradation.
Dust- and Splash-Proof. Allows you to keep shooting when conditions get iffy, provided your camera and lens are also weather-sealed.
Please Note: We carry this teleconverter in multiple mounts. This is the Canon version.
