Compatible with both DSLR and Mirrorless

SIGMA Global Vision (Art, Sports & Contemporary) lenses for Canon EF and Nikon F mounts are not only compatible with DSLR cameras, but mirrorless cameras as well, including Canon EOS R and Nikon Z bodies. With an OEM mount adapter, you can take advantage of the performance benefits that mirrorless cameras deliver with your favorite SIGMA lenses. And for Sony E or L-Mount camera users, you can adapt EF mount lenses with our MC-11 and MC-21 Mount Converters.


Make sure you get your 4-Year Warranty

All SIGMA lenses come with a 4-Year Warranty in the US, but only if you buy from SIGMA America directly or a SIGMA Authorized Dealer. Grey market importers undercut legitimate retailers, deceive well-intentioned customers, and sell products that are ultimately not eligible for warranty service. Make sure you are buying from a trusted source so your lens is covered!
