It has been a while since that February announcement of the new Sigma MC-11 mount converter. The device which promises to adapt Canon EF and Sigma SA mount Sigma lenses to Sony E/FE mount bodies. This week Sigma finally got all of their ducks in a row and had announced the official pricing and availability of the new device.

According to the Sigma release, the new MC-11 will be available starting April 22nd, 2016 and will retail for $249. In addition to the availability announcement, Sigma announced some lens kits they will begin selling which pair the new MC-11 with the popular Sigma 34mm F/1.4 Art and 50mm F/1.4 Art.

The promise of these adapters from Sigma is that they will offer superior performance over similar adapters. The way they will do this, according to Sigma, is by overriding the firmware on the lens and replacing it with Sony AF firmware, allowing the lens to talk directly to the camera via the adapter. So, rather than the adapter translating the camera/lens commands, it is teaching the lens how to speak Sony. There have been some tests that have come out, but nothing conclusive nor unbiased to give us a true idea of the sort of performance one can expect out of these.

Sigma MC-11 Feature Highlights

  • Adapt Canon EF-Mount Lens to Sony E Body
  • Integrated LED Displays Compatibility
  • Maintains Autofocus and Auto-Exposure
  • Supports In-Camera Correction Features
  • Flocked Interior Reduces Reflections
  • Retains EXIF Data

The caveat to the new lens kits are that they will be limited to 5,000 units worldwide, so your chance of being able to purchase one may be fairly limited. According to the Sigma release (in Japanese, translated via Google), the 50mm F/1.4 kit will be 164,500 Yen (just under $1500 when converted to USD). So far no US stores have listed these new kits for sale, so we are still waiting to see if they will even make it stateside. But really, if they don’t you are not missing much – simply go out and buy the lens you want along with the MC-11.

At any rate, you can pre-order the Sigma MC-11 Mount Converter now over on B&H. Doing so now will likely get you near the top of the list to get one once Sigma starts shipping them out on April 22nd.
