    yes it is entirely possible.

    just make sure you don't accidentally get the Sigma APO teleconverter, because it will not work with the 105mm macro.

    you will lose 1 stop of light with a 1.4x TC and 2 stops with a 2x TC.

    minimum focusing distance will be nearer when you use a TC.

    Minimum Focusing Distance will REMAIN the same after you put on the TC.
