Review on Enhance Your Sony E-Mount Camera with Sigma MC-11 Lens Mount Converter (Canon EF). Includes Bonus 32GB SD Card! by Telly Roden

Received this as a gift at first but the recipient says it works great on their Sony A6000 with a Canon 24-105 lens I loaned them have. AF and IS work as expected, but maybe a bit slower compared to Canon's native body. However, he ended up returning it as the body of the A6000 is quite small and after installing the Canon adapter and lens he found it too bulky for the job. I'm more comfortable with the A7 full-frame body with a handle to balance the lens. Overall, this was a great deal for the retail price of $149.
