The Pros & Cons of the Sigma MC-11 Adapter (Canon EF to Sony E)

A review and discussion of the Sigma MC-11 adapter, to adapt Canon EF lenses to the Sony E mount system. In this case, the photography end of it works well, but there are some shortcomings of the adapter I highlight for anyone on the market for such an adapter to switch systems. (Or to share EF lenses between two systems.) Of particular shortcoming is the lack of video autofocus with the adapter, and the lack of weather sealing. #adapter
