For Sony & L-Mount shooters

SIGMA's DG DN lenses are made exclusively for mirrorless cameras, including Sony E-mount and L-Mount (SIGMA, Panasonic, Leica, and others) systems. These full-frame lenses are designed to take advantage of the benefits offered by mirrorless camera bodies, including more compact dimensions, in-camera corrections, and a variety of improved technologies.


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!
