Anyone tried a mirror lens with the AF 1.7x TC? Will it autofocus?

I have a Sigma 600mm and used it with the AFA1.7x and Yes, once you are close, the adapter is able to finetune your focus, (obviously depends on light conditions and the contrast/point you are focusing on) But remember the " In focus" on a mirror still fairly short DoF so it really can be hit and miss.
