Optimized for Canon EF-mount lenses in the Global Vision line, the TC-2001 2x Teleconverter from Sigma will offer an increase in focal length of 2 times for select Global Vision lenses. This model offers full communication between the lens and camera and will allow autofocus to operate at up to f/8. The teleconverter also features two Special Low Dispersion elements for reducing the appearance of chromatic aberrations and maintaining quality. Additionally, for protection, the TC-2001 is both dust and splashproof. When attached, the 2x conversion results in a light loss of approximately two stops. A soft zippered carrying case is included to protect the teleconverter when not in use.

Which lenses are compatible with the Sigma TC-2001?
This teleconverter is optimized for Sigma lenses from the Global Vision line with Canon EF mount. For the exact list of compatible lenses, we recommend checking the manufacturer's specifications.
Do I lose image quality when using a 2x teleconverter?
The TC-2001 incorporates two Special Low Dispersion (SLD) elements that help minimize chromatic aberrations and maintain optical quality. However, as with any teleconverter, there may be a slight loss of sharpness and a reduction in brightness (approximately two stops of light).
Does autofocus work with this teleconverter?
Yes, the TC-2001 allows autofocus with apertures up to f/8. This means that if your lens has a maximum aperture of f/4, when doubling the focal length it becomes f/8, and AF will still work on most cameras.
What warranty does this second-hand product include?
This used teleconverter has been inspected by Camera Market and is offered with a warranty of 6, 12, or 24 months, depending on the option you choose. This way you buy with total confidence.
