The TC-2001 from Sigma is a 2x Teleconverter specifically designed for Sigma SA mounts. Designed with 2 Special Low Dispersion glass elements, you will experience superb image quality. This teleconverter increases the focal length by 2x for select Global Vision Sigma lenses. It employs full communication between the lens and camera, allowing the autofocus to operate at up to f/8. Sigma constructed this teleconverter to be dust and splash proof so you can shoot confidently in a variety of challenging conditions. When attached, the 2x conversion factor results in a light loss of approximately two stops.

This teleconverter was created as part of Sigma's exclusive Global Vision line with wide compatibility, even working with large-diameter lenses. Get maximum AF and twice the standard reach, optimizing your compatible lens.

SLD glass Elements

TC-2001 incorporates 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 Large Diameter lenses

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.

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

Ease of Use

A rubber part is attached to where it mounts with the original lens, and it prevents the devices from scratching each other. It has the same materials and finishing for integrated design as the lenses from the new product lines.

Compatibility:

  • Sigma 120-300mm f/2.8 DG OS HSM Sports Lens
  • Sigma 150-600mm f/5-6.3 DG OS HSM Sports Lens
  • Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary Lens
