This new f/2.8 telephoto zoom from Sigma is the answer to many photographers' prayers. As lenses go, this one is rather short on what you could class as key features, but that doesn't mean that it's below par. In fact it sets the benchmark on what a telephoto zoom should offer.

The best for dx cameras!

According to dxO labs this is the best lens for Nikon d7100! So I bought it and after a few hundreds shots I defenetly can confirm that! It's amazing! Great quality and outstanding photos!
