Sigma Announces New ART Lenses and MC-21 L-mount Adapter
As part of its L-mount alliance, Sigma unveils new adapter and an impressive lens line.

Since news of Sigma’s partnered alliance with Leica and Panasonic on their collaborative L-mount system for APS-C and full frame cameras, Panasonic has since introduced the world to its new 4K full frame digital cameras - the LUMIX S1 and LUMIX S1R.
Since specs have been leaked in advance of the cameras' release sometime in April, early hands-on reviews of the more video-focused LUMIX S1 have been largely positive. Leaving many anxious to see what new lenses Sigma would roll out along with an adapter to go between Sigma SA or Canon EF to the L-mount.
Now, it appears we have our answers with these 11 new Sigma ART lenses and the Sigma MC-21 L-mount adapter.
