So I just got my Sigma MC-11 today and tried it on two lenses, my Canon 70-200 2.8 IS Mark I and Tokina 300 2.8 on the a6300. It works very well on my Canon 70-200 2.8 IS Mark I. There is a little hunting but not bad at all. If you put the the focus limiter on, the hunting is almost gone completely.
On the Tokina 300 2.8, I was surprised it worked as well! Keep in mind the Tokina 300 2.8 is an older lens. I used it on my 5D3 and it autofocused quick with a slight noise due to focus motor of lens. On the a6300 with MC-11, it\'s s bit slower and hunts more than the 70-200 2.8 IS I, but still useable for portrait work and general shooting. A trick I use for it to focus faster is to prefocus close to the desired point and it locks on quickly using AF-S and AF-C. I even tried a Kenko 1.4 DG X teleconverter and works great on both the lenses. I will post images and video soon.
