The Sigma 2x Teleconverter TC-2001 Teleconverter is developed exclusively for Canon lenses. By mounting it in between a telephoto lens and a camera, the magnification of focal length of TC-2001 is 2x.
It incorporates SLD (Special Low Dispersion) glass elements that offer excellent aberration correction.
Incorporating SLD glass elements for better image quality
TC-2001 incorporates 2 SLD (Special Low Dispersion) glass elements. By minimizing chromatic aberration effectively, it has achieved very good optical performance, thus it is possible to maintain the optical quality of the original lens.
Compatible with lenses of large diameter
Its power distribution is designed for lenses of large diameter. Without affecting the lens performance, it offers stable image quality until corners. The rich peripheral brightness enables shooting quality images at every focal length.
Durable dust and splash-proof construction
It is dust and splash-proof, and designed for higher durability. Sigma 150-600mm F5-6.3 GD OS HSM Sports and other telephoto lenses are able to meet the demands that professional photographers would require in severe shooting conditions, such as in the rain.
AF is effective up to F8
When the Sigma Teleconverter is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF.
