Created exclusively for the Global Vision lenses, these teleconverters ensure the utmost in compatibility, even for large diameter lenses. With effective AF at F8 and 2x the reach, get the most out of your Sigma lens.

Incorporating SLD glass elements for better image quality

TC-2001 carries 2 SLD (Special Low Dispersion) glass element. 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.

The durable dust and splash-proof construction is suitable for professional use

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 new SIGMA Teleconverter is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF.

Evaluation with SIGMA's own MTF measuring system "A1"

We used to measure lens performance with an MTF measuring system using conventional sensors. However, we've now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA Teleconverter TC-2001 will be checked using this "A1" before they are shipped.
