Though I may be stating the obvious, the dock is used with the Canon mount version of the lens (which I use with the MC-11) . Any updates for the E mount version would be done through the camera.

Not a Doctor, PaulD was taken, so I added the second letter of my last name.

Oh, hmm ... I thought it was already out. It was strongly rumored on many sites several months ago:

Kind of annoying that they have one for L mount, but not for E mount. I wonder if they ran into trouble because of the E mount license agreement which also prevents them from offering E mount teleconverters. On the other hand, Samyang has an E mount dock. Maybe their terms are different?

BTW, I suggested this because there was a thread here previously with an MC-11 user who was able to correct misfocusing issues with his EF mount Sigma lens using the dock.
