So as many of you know I really like shooting with both native and adapted lenses on my Sony mirrorless bodies. When it comes to shooting with Canon lenses I've been using the Metabones Mark 4 Adapter with some pretty awesome results in regards to Auto Focus. There are a ton of adapters that work just fine for manual use, but when it comes to auto focus and transferring exif data you have to be more careful.
There are other adapters out there like Fotodiox, Vello, etc. but all of them really lag behind the performance of the Metabones as it relates to acquiring focus, reliability, build quality and more. And the Metabones is definitely more expensive, so it makes sense that we should expect more.
Well earlier this year Sigma announced their brand new adapter, the Sigma MC-11. I first tried it in March when it was very new while at the WPPI convention. Since I already had the Metabones I saw no real need to pick up the Sigma. It worked well, but there was no marked improvement over the Metabones especially when using Canon lenses. I didn't own any Sigma lenses so I didn't purchase it.
Fast forward to last month where I attended PhotoPlus in New York City. My followers had asked me quite a bit about using this adapter and also wanted to know about the Sigma Art lenses. I became quite interested in the Sigma 20mm f/1.4 lens and once that happened, I wanted to try it on the Sigma MC-11.
So I purchased the adapter and the Sigma 20mm and gave it a go. The first thing I noticed was that the Sigma performed just about as well as the Metabones did with the Canon lenses that I owned. In fact, the very first shoot I ever did with the Sigma MC-11 was on the Canon 85mm f/1.2 lens.
I then had the opportunity to use the MC-11 with the 20mm on my commercial shoot for Mia Bella Couture. It was pretty awesome. I have to say that the Sigma MC-11 Adapter with the Sigma lenses is about the closest thing to using Sony native lenses. In fact there are virtually all the options using Sigma lenses with the MC-11 Adapter that we enjoy on Sony native lenses including; Eye Auto Focus, All the Focus Modes and Focus Areas etc. Many of these options are missing when you use the Metabones adapter, or when you use the Sigma Adapter with Canon (non-Sigma) lenses.

So in short if you want the closest experience to native lenses you choose the Sigma MC-11 Adapter with Sigma lenses...and I especially love the Art lenses. Make sure to check out Sigma lens compatibility chart as well before purchasing a lens. The Sigma MC-11 will work with both Sigma lenses and Canon mount Sigma lenses on your Sony body.
If you are coming over to Sony as a Canon shooter and want to use your lenses on a Sony body I'd give the slight edge to Metabones as it relates to Autofocus...but not by much. There's also a good edge to the Sigma adapter as it is $150 less than the Metabones which is significant.
I plan on doing a full on shoot and comparison between the Metabones Mark 4 Adapter and the Sigma MC-11 Adapter in the near future. To see my current review of the Metabones Mark 4 Adapter please click HERE.
Below are shots taken with both Canon EF lenses and Canon mount Sigma lenses on the MC-11 Adapter. I hope it helps!
