I’m a well-known pro and specialize in tech and imaging reviews. If you are reading this review you already know the Sony mirrorless cameras are terrific. Like me, you are likely looking for ways to use your excellent Canon glass with the Sony system. Simply stated, the Sigma MC-11 is a terrific solution. But be aware that it’s not a miracle maker:
PROS:
No loss in optical quality.
Great build and ease of use.
A fair price.
Most Canon EF and other lenses will work with quite good focusing speed and tracking.
CONS:
Some lenses are outliers so be sure you have latest firmware installed.
You may like Sony lenses for typical lighter weight. The MC-11 adds 4.4 ounces to lens weight.
OBSERVATIONS AND TESTING:
I did an exhaustive test with my high end Canon lenses, using them with the 61 megapixel Sony A7R IV. A camera with this type of truly incredible resolution will really show differences although in most uses, minor differences in lens sharpness are not as discernable as what I’ll discuss here:
My Canon lenses are great. The Sony lenses, in almost every case, are better yet. Thus, if you are using a camera with crazy high resolution like the A7R IV, you may want to switch to Sony lenses sooner rather than later. Depending on the Canon lens tested, focusing is really good, but fast tracking for sports and wildlife is a bit behind native Sony lenses. The best Sigmas and Tamrons optimized for Sony will also sometimes beat Canon lenses for speed and tracking.
I tested Canon EF lenses including 16-35 f2.8, 16-35 f4, 24-70 f4, 70-200 f2.8, 70-200f4, 24 IS, 300 f4 IS, 1.4x TC. They all did a great job. Particularly, I’m seriously considering hanging onto my wonderful 70-200mm and 300mm Canon’s for use with the MC-11. Sony does not yet have quite the perfect match for me in those focal lengths that match light weight with pro performance. The only lens disappointment for me was the otherwise wonderful Canon 100 f2.8 Macro. It hunts for focus and was not a good performer with the MC-11.
CONCLUSION:
The price is right compared to the competition from Metabones that I have not yet tested. However, I don’t feel I need to. The Sigma MC-11 looks great in combination with Canon lenses and Sony bodies, has a build quality to match, and is the ideal bridge to meet the advantages of Sony system over my old amigo Canon.
Hope this long review has been of some small help. HAPPY SHOOTING!

Doesn't work with all lenses
Great deal at the time I bought and a neccessity since I was switching to a Sony A7III. Before using make sure to check that it's updated to the most recent firmware. Once I updated I tried several lenses including a Tamron 150-600 G2, a Sigma 150-60 C, and a Tokina SD 16-28 F2.8. The first two worked to expectations considering they aren't native lenses to the Sony but I had issues with the Tokina regarding no AF. The photo was taken using the MC-11 with the Sigma lens. Shipping was fast and easy and it came in the manufacturers packaging.
