Tele converter for Sigma Global Vision lenses

The Sigma TC-2001 doubles the focal length of compatible Sigma Global Vision lenses for Nikon mount. It incorporates two SLD glass elements to maintain optical quality across the frame. The converter is built with splash and dust proof construction for durability in challenging conditions. It is designed exclusively for Global Vision series lenses to ensure full communication and performance.

Sustained use with splash and dust proof sealing

The sealed barrel protects internal optics from moisture and particulate ingress during extended outdoor sessions. This construction helps maintain consistent image quality and autofocus reliability over long periods of use. Effective autofocus at F8 supports continued shooting as light levels change. The robust build is intended for long lasting durability in the field.

Check lens compatibility before ordering

This teleconverter works only with Sigma Global Vision lenses; it will not function correctly with other Sigma lines or third party lenses. Verify that your specific lens model is on the supported list to retain autofocus and metering. The converter adds two stops of light loss, so confirm your camera handles autofocus at the resulting effective aperture. Ensure your Nikon body communicates properly with Sigma Global Vision optics.

Questions about this item

How much extra weight does the 0.64 kg converter add to a full-day shoot?

The converter itself weighs 0.64 kg, so your total kit weight increases by that amount during extended use.

Which specific Sigma Global Vision lenses must I already own for the TC-2001 to function?

It is designed exclusively for Sigma Global Vision lenses; compatibility with other mounts or brands is not supported.

Will autofocus still operate at F8 when I pair this 2x converter with my older Sigma DG lenses?

The TC-2001 is created exclusively for Global Vision lenses, so AF at F8 is not guaranteed on earlier DG series optics.
