The Sigma Art 24-35 is a brilliant piece of glass. It's incredibly sharp, even wide open, as most Art lenses are. The f/2 allows it to function pretty well in low-light, giving you the popular 24, 28, and 35mm focal lengths all in one lens. The close focus ability will get you some very shallow depth-of-field, as evidenced by the last two images, taken with the lens and the Nikon Df. I'm only selling it because I just don't find myself reaching for it very often. I prefer a tighter focal length of around a 50mm, and it's bulky enough that bringing it alone "just in case" often doesn't feel worth it for just a couple of shots. It's time for it to find a new home. It would make an excellent wide-portrait option, as you can get background context with very pleasing out-of-focus rendering, and having 3 focal lengths in one gives versatility without having to swap lenses. It's in excellent condition - I baby my gear. When I got it from MPB it was missing the lens hood, so I bought a brand new one from B&H.
