Sigma MC-11 super test! 24 Canon fit lenses tested

Welcome to our super test of one of the most exciting new products from Sigma, the MC-11 EF to Sony E mount adaptor.



The Sigma MC-11

This great piece of kit from Sigma is designed to allow fully compatible use of the Sigma lenses in Canon EF on Sony E mount cameras, including full frame FE mount cameras like the Sony A7SmkII, A7RmkII and A7mkII.

Greg Thurtle from TP Photography, who helped me complete this mammoth test, joined me in store as we went through many Canon L series lenses and other third party lenses to see how well they perform. As this adaptor is not supposed to support these lenses, the results would be very interesting. If it worked well, the MC-11 could be a much more cost effective alternative to the popular Metabones adaptors. The list of lenses tested is listed below, watch the video to see how well they performed!
