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!

Diffraction MTF Chart
?
Diffraction MTF takes diffracted light at every aperture into account which is very close to actual image data. Geometrical MTF does not consider the diffraction quality of light, yet it tends to show higher values than actual image.
