The build quality of the lens is excellent thanks to high quality materials assembled with very tight tolerances. The broad, rubberized zoom and focus rings operate both very smooth and even slightly damped - a rare characteristic these days.

Great zoom lens with large aperture! Being able to get telephoto with f/2.8 is what I needed and the lens produces great pictures on my Nikon D7000. Build is very solid, zoom and focus rings are smooth. Only issue is its a bit heavy, but what do you expect from lens with this capability.

Sigma's new APO 50-150mm f/2.8 EX DC OS  HSM lens is one of only two large-aperture tele-zoom lenses for cameras with APS-C sized sensors. (The other is the Tokina AT-X 535 Pro DX AF 50-135mm f/2.8.

You need a fast; effectively-stabilised lens for portraiture or product photography; You want a zoom lens that can be used with polarisers and graduated filters; You require good flare resistance in backlit situations.

You have a camera with a 'full frame' (36 x 24mm) image sensor, You need a small, lightweight lens; Don't buy this lens if, You have a camera with a 'full frame' (36 x 24mm) image sensor, You need a small, lightweight lens

I really like this lens. It is my first "professional" grade lens and I am VERY impressed. The sharpness of my photos is a magnitude above that of the kit lens for my Canon T3i. Photos taken with this lens are tack sharp! I read some reviews stating that at F2.8 there is softness at the edges.

Much Cheaper Than L Glass; Quick Focus; Very sharp

Heavy; Large; Not For Full Frame Camera

I have been waiting for this lens for a year. Finally I bought it one week ago. Let me tell you it is a Sharp lens! Tamron and Sigma are catching up with Nikon and Canon. This is actually a pro lens to DX shooters with optical stabilization.

Great lens, I haven't came across any problems with this lens, it has a great focal length especially with a crop factor of about 1.5x. The only cons I can think of is it dosnt have the quickest focusing when it comes to sports, also i would of liked to see the manual mode button on the side, lastly...

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.

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!

It focuses fast and accurately; IQ is superb, almost good as Nikons' 70-200mm; It is almost as heavy too. Build quality is excellent and image stabilization works well, about 3 stops.
