Sigma MC-11 Mount Converter

Zeiss Loxia 50mm - Noosa Beach Life Guard
From the reports, Sigma's MC-11 is beginning to ship.

I'm looking forward to seeing one in the flesh. Even without the benefit of firsthand experience, I believe the MC-11 will be an significant advance for E-Mount users because this is Sigma firmware driving Sigma hardware. No code cracking or interpreting. The results should be lenses operating as they would if they were provided in native E-Mount.

If the MC-11 is foreign to you, have a look at Sigma's 2 minute shown below.

2 May Update:

It seemed clear to me from the Sigma site and the video that the MC-11 is only intended to work with a certain selection of Sigma lenses. And, it's not touted for video or even autofocus continuous. There's even an LED on the side of the converter to alert the user to the compatibility of any attached lens. Nevertheless, there's a reviewer calling for a firmware update because the MC-11 isn't working well enough with Canon lenses.

More concerning, however, is a report that the converter causes focus jitters at the smallest f/stops with the 50mm f/1.4 Art.
