Question about Sigma TC-1401 Tele-Converter 1.4x Canon
Does the Sigma TC-1401 teleconverter 1.4x fit a Canon EF 70-300mm 1:4-5.6L IS USM and the Canon EOS 70D?
Helpful answer
Hello, it definitely fits the 70d, but as far as I know only with certain Sigma lenses. Just write to Sigma customer service. They give good information.
Here is the official compatibility list. Only Sigma lenses are listed.

No, it only fits a few Sigma lenses and only Canon extenders fit Canon lenses.
