Sigma 400mm f5.6 teleconverter options know to work

I have this lens I got from my dad's Maxxum outfit. I'm using via adapter on on a Blackmagic Pocket 4K for video and it's working great.

But trying to figure out what teleconverter's will actually work. I found this page https://www.dyxum.com/dforum/amount-teleconverters-guide_topic2100.html

But many of these are not available or not tested. For sale, the best buy seems to be Sigma 2X APO EX DG Tele Converter, but since this is not an APO lens, I'm worried it won't work.

Anyone have this lens with a teleconverter?

Thanks

Stephen

The Sugma teleconverter chart for A Mount which used to be on a Sigma website appears to have disappeared.  However, from memory, Sigma APO teleconverters were made to only fit APO lenses, and will not mount on non APO's.
