Huzah! Sigma is finally ready to push further into the E-Mount market (and more into micro four thirds as well) with the announcement of the E-Mount/Micro 4/3 mount 30mm f/1.4 Contemporary lens as well as the Metabones-like MC-11 Mount Convertor. Sony fans, and myself, have been waiting for this day for quite a while, and Sigma’s entry into the market with this lens says two things: 1) This is only the first of many and 2) There are enough Sony users out there to pull demand for increased effort from Sigma for dedicated optics.

Let’s start with the new lens, the full name of which is the Sigma 30mm f/1.4 DC DN Contemporary Lens. Being in the “Contemporary” line of lenses, we can probably expect this lens to still perform well while commanding a lower price point than “Art” line lenses do.

Contemporary Line Performance and Value

Represents first affordable F1.4 performance lens for the mirrorless market

Sigma engineered quality within a sleek compact design

Fast, smooth AF stepping motor designed to support video (yay!)

Features one aspherical element and one double-sided aspherical element producing imaging quality comparable to the Art line.

Features 9 elements / 7 groups, 52mm filter thread, Minimum Focus Distance: 11.8in, Weight: 9.3oz, Dimensions: 2.6×2.9in.

The new Sigma 30mm F1.4 DC DN Contemporary Lens will be available in Sony E-Mount and Micro Four Thirds mount. No price or release date were given yet.

Second is the MC-11 Mount Convertor that allows Sony camera users to utilize 19 Global Vision lenses in Canon Mount (EOS) and Sigma Mount (SA). It looks very similar to what we see out of Metabones, but with Sigma optical design and hardware that is designed specifically to work with Sigma lenses.

“There are many challenges to designing high-quality mount converter and topping the list is aptly handling phase detection AF in newer cameras and this is where the Sigma MC-11 is groundbreaking in its support for the Sony E-mount systems,” states Mark Amir-Hamzeh, president of Sigma Corporation of America. “The new Sigma MC-11 mitigates complications with a purpose-built lens control data system engineered for maintaining superior AF functionality. So the growing number of Sony E-mount camera users who have been asking for more lens options, now have access to a large pool of lenses that fully embody Sigma’s signature quality and performance.”

The Sigma MC-11’s LED display lets Sony users know if the attached Sigma lens is compatible and whether or not the MC-11 needs to be updated for that specific lens.

Its internal control data system keeps detailed information on each compatible Sigma lens, automatically optimizing performance of AF drive, aperture control and other critical lens functions. The MC-11’s internal control data system also maintains continuity with key camera functions that control brightness and correct transverse chromatic aberration, distortion, and more. The complete compatibility with both Sigma lens OS and Sony in-camera OS ensures correction of camera shake and other stability issues and when used with in-camera stabilization, MC-11 allows angle shake correction in the lens. The integrated flocking helps prevent internal reflections and reduction in lens performance. In addition, the MC-11 retains important EXIF data ensuring users can analyze every detail of their lens setting.

The Sigma MC-11 converter can be updated with the latest compatible lens information from a workstation or laptop using the Sigma Optimization Pro software and Sigma USB Dock (sold separately).

It will be interesting to see if there is any difference between a Metabones adapter and the MC-11.

Below is a chart that explains which lenses can be used (or are necessary) with the MC-11 on specific Sony cameras.
