Summary: I've been using this lens as my main lens for almost three years with a Nikon D7000 and I couldn't be happier. Some reviews said it was soft at f/2.8 but I have not noticed that. It's built extremely well, is wide, fast and reasonably priced. What more could I ask for? This lens extends as you zoom out, something to keep in mind. The constant f/2.8 is great and it can focus very close. Does NOT autofocus on entry level Nikon cameras like the D3xxx/D5xxx/D40/D60.
Summary: This lens is a jewel. I took it to NYC and it never left my D-90. All the images came out sharp and contrasty. NYC photos above are mine. It focused well and the images look great even wide open. I like the quick switch to manual mode as well. Certainly a great walkaround and event shooting lens. Would buy again!
Summary: Well worth the money spent. If I could afford the Nikkor 17-55, I would have bought that...but at more than half the price, the Tokina 16-50 is awesome. If you have read some other reviews, some state that wide open at 2.8, the pics can be slightly soft? umm..its not an issue 95% of the time. This is my first pro lens outside of my kit 18-105 for my D90. Compared to my 3.5 this 2.8 Tokina is sharp !
Summary: Great Build Quality! Great Value compared to the double priced Nikon 24-70mm 2.8 and the cheap build of the Tamron 17-50mm 2.8. I own all three lenses and was shocked to see the quality of images that this Tokina Lens produces. Sure the Nikon is slightly better but for more than double the price? No thanks. The Tamron also produces quality pics but autofocus was inconsistent and the build is so CHEAP.
Summary: Worked perfectly out of the box. Very sharp, good contrast, fast focus, sligt CA that is easily corrected in PS. Only visible in high contrast areas and only at 100% magnification. Colors may be slightly on the cool side. Compared to the Nikon 17-55mm 2.8 at double the price you get same sharpness, smaller size and less weight. Tokina's Pro series are built very well and have good optical qualities. Nice damping of zoom ring and nice feature for manual/auto focus.
Fast lens at F 2.8 and performs well in poor lights conditions

Summary: Most of the times I use a Canon EF 24-105mm f/4 L IS USM Lens for Canon EOS SLR Cameras as an all-round lens (mounted on an EOS 450 first, then EOS 7), and I was looking for a somewhat wider angle, but not too wide. I love Tokina 11-16MM F/2.8 ATX 116 Lens for Canon EOS AF Digital - Tokina ATX116PRODXC , so I bought this one and so far I've been super happy about it. It's a fast lens at F 2.8 and performs well in poor lights conditions, solid, but not too heavy.
Summary: This is my main lens on the Canon 7D. Previously used a Sigma 24-70 on an XT. Very sharp. In practical use, the focus is nearly as fast as Canon USM with only a tiny amount of noise. However, in super dim conditions, and I mean super dim, the lens can't focus. In those conditions, I switch to the Canon 50 1.4, which the 7D can focus with in practically dark conditions. Great built quality.
Summary: I sold my Canon 17-40 f/4 and Sigma 24-70 f/2.8 and got this lens. It's definitely better than the Sigma and is almost up there with the Canon when it comes to colors and sharpness. I got sick of carrying 2 lenses for different occasions. It's a bit wider than the usual "normal zooms" and is 2.8 all the way which is quite nice. Everyone keeps saying that the CA is large, I don't much care about that. You can correct CA.
Summary: Just bought this lens and am very happy with it. The build quality is excellent and so is the speed and sharpness of this lens. The wide end of the range is also significantly wider than the 18 mm of the Nikkor kit lens I got with the D90 (and which this lens is now going to replace).
