I would like to buy a Sigma 1.4 TC to use with my Sigma 70-300mm f4.0-5.6 DG OS and my Sigma 50-200 f4.0-5.6 DC OS lenses. Is there potentially a compatibility problem? Will there be any physical interference?

The Sigma TC does stick out past the mount and would either not mount or would cause a problem at some zoom settings where the elements would collide.
