I have the Sigma 70-200 f2.8 and have tried it with a Nikon 2x and 2 other converters with a D610. In all cases the images with the TC were of lower quality than cropping an identical image from the lens itself. Problem with all TC's is that they magnify all the defects in the parent lens, by the square of their magnification, and add in allignment tolerances etc. They may work with older DSLRs, but the newer sensors are too much for them.
