Does anyone know which brand of 2x TC

Not quite sure what you are trying to ask here. I am assuming that you are looking for a teleconverter that is compatible with EF-s lenses. If this is the case I'm pretty sure that there isn't one available from Canon for the EF-S line as there is rubber protruding out of the teleconverter and it will interfere with an EF-s lense as they can extend out of the lense housing.

The teleconverters will only work with EF lenses unless you use an extension tube that can take an EF-s lense on one side and connect to an EF or EF-s lens mount on the other. You will however lose infinity focus with such a set-up though.

You could probably use one from Kenko/Tamron since they don't have the protruding front element. They work on nearly any EF lens, so they very well may fit on EF-S. Just remember, for a 1.4x TC you lose 1 stop of light, and for a 2x you lose two. That may mean your camera no longer autofocuses with your lens, and it's manual focus only. Very likely since most EF-S aren't very fast lenses. You'll also lose some IQ when using TC's. With the 2x moreso than with the 1.4x. In short, I wouldn't recommend using TC's with EF-S lenses in general.

I don't think there are any EF-S lenses that would still retain AF even if you did find an acceptable TC.

I can assure you that the EF-S lens does not accept any Kenko Converters which is why I steer everyone from purchasing the EF-S lenses.

No EF-S lens will fit with any teleconvertor.
