Sigma APO 1.4 Teleconverter

Actually I wanted to get the Kenko just because it seems thats the one everyone is using, but now I found this one.

Does anyone have experience with this one?

Does autofocus work with canon 100mm usm and tokina 10-17?

Any feedback would be awesome!

Thanks, Morten.

There is a compatibility chart at sigma that suggests that you will not get autofocus except with a few lenses which is why most folks are using Kenko/Tamron but I can't find the details on if the Tokina will work.

Thanks for the reply! Found a few compatibility charts and it seems that the Sigma TC only really works (AF) on Sigma lenses.

Got myself a Tamron 1.4, friend brought it over from Bangkok. Had a single dive with it, but I need to practice a lot more, I'm finding that its hard to get the sharpness that I'm used to with just the 100mm. I was doing manual focus, which was also a first time for me with the 7D, will give an update on the matter once I get a bit more experience with it
