Sigma ART Lens Sale returns (until Dec 25)

The Sigma ART lens sale is back on again with a variety of Sigma ART DSLR lenses participating. You can find them nicely organized at Adorama, sorted by mount: Canon EF, Nikon F, Sony A, Sigma SA, Pentax K, and a couple of Sigma lenses to Sony E mount lens converters too. There are too many to list here individually at the moment.
