I have a Minolta HTSI Plus. I wan't a 2x teleconverter to double my 70-210 lens.

Will I get better results buying this teleconverter insead of buying an off brand auto focus teleconverter?

Well Brian, in a manner of speaking, the Sigma 2X is an off brand. You don't say what the aperture of your 70-210 is but remember that whatever it is you will lost two stops and considerable emage quality.

The Sigma APO EX teleconverters are designed to work with lenses with recessed rear elements. I have the 1.4x version, and it mounts on my Nikon 80-200/2.8 and 300/4, but not (not that I'd want to, but I checked anyway) on my 70-300/4-5.6 or any of my lenses in the wide, standard, or short telephoto group. So, make sure it'll fit your lens.
