No unfortunately not. I don't find any information about that.

It definitely will affect the AF because it is not an native RF lens, you might not get the same amount of keeper shots but it certainly is a good entry into the systen. But don't expect to photograph fast action and getting reliable af.

Hello, Yes, I myself bought the TC-2001 and its little brother, the TC-1401 (1.4x) and they work very well with this zoom. However, contrary to what is noted in the description, it is not compatible with the "C" versions of sigma lenses. I also have a zoom lens from this series and it cannot be shown on the TC-2001 and 1401.

Yes the lens is 100% compatible. But also heavy 😉

Canon only refers to its own glass: http://gdlp01.c-wss.com/gds/7/0300015307/02/ext-ef14xiii-2xiii-im2-ger.pdf Sigma teleconverters (TC-1401, TC-2001) support the lens: https://www.sigmaphoto.com/lenses/lens-resources/teleconverter-compatibility
