Re: Teleconverter for the 18-400mm?

One thing to keep in mind about the 100-400 lens from Sigma, it does auto focus with tele-converters. You can mount a tele-converter but it will not auto focus with one, this was one reason why I moved to the Tamron 100-400. Check Sigmas website the 100-400 C is not in the compatible lens list.  I could never get the 100-400 C to work with the Sigma TC-1401 on my 7DII.
