FAQs

Which lenses are compatible with the Sigma 2x Teleconverter TC-2001?

The Sigma 2x Teleconverter TC-2001 is exclusively designed for Sigma Global Vision lenses, including the Art, Sports, and Contemporary series. Check the Sigma website for a full compatibility list.

Does the teleconverter affect image quality?

Using a teleconverter can slightly reduce image quality compared to using a prime lens. However, the TC-2001 includes SLD glass to minimize aberrations and maintain image sharpness. Properly using the lens can mitigate some quality loss.

Will the teleconverter affect autofocus speed?

The teleconverter can slightly slow down autofocus speed. However, it supports autofocus up to f/8, allowing for effective autofocusing with many compatible lenses.

How does the teleconverter affect the lens's aperture?

The Sigma 2x Teleconverter reduces the maximum aperture of your lens by two stops. For example, a lens with a maximum aperture of f/2.8 will become f/5.6 when used with the teleconverter.

Is the teleconverter weather-sealed?

Yes, the teleconverter features dust- and splash-proof construction to protect against the elements.

How do I clean the teleconverter?

Use a lens cleaning cloth to gently clean the front and rear elements. Avoid using excessive pressure. You can also use a lens cleaning solution for stubborn marks.

Can I use the teleconverter with non-Sigma lenses?

No, the Sigma 2x Teleconverter TC-2001 is designed exclusively for Sigma Global Vision lenses.

What is the warranty period for the Sigma 2x Teleconverter TC-2001?

The warranty period for Sigma products, including teleconverters, varies by region. Please consult the documentation that came with your product or the Sigma website for specific warranty details.

Troubleshooting

Autofocus not working.

Ensure your lens and camera are compatible with the teleconverter. Check that your lens has enough light for AF to function. Clean the lens contacts and teleconverter contacts.

Images are soft or out of focus.

Ensure correct focus settings on the camera. Check for camera shake and use a faster shutter speed. Clean the front and rear elements of the lens and teleconverter.

Metering issues or incorrect exposure.

Check your camera's metering mode and adjust exposure compensation as needed, as the teleconverter reduces the effective aperture. Ensure the lens and camera contacts are clean.

Teleconverter not mounting properly.

Make sure the lens is a compatible Sigma Global Vision lens. Align the red dots correctly, and ensure no obstructions are preventing the mount.
