Best ultra wide-angle lens for nikon dslrs: 8 tested

Tokina 10-17mm f/3.5-4.5 AT-X107 DX - £510/ $670

Out on its own, this is the only fisheye zoom available for Nikon cameras. You can go wild with extreme barrel distortion for really funky images, the effect being most pronounced at the 10mm end of the zoom range. As is typical of fisheye lenses, it's considerably smaller than regular ultra-wide zooms, and weighs a mere 350g. The built-in hood doesn't allow filters to be fitted, which would cause massive vignetting. But, as with all Tokina lenses, overall build quality is great.

One benefit of the fisheye effect is that you get a full 180-degree angle of view at the 10mm zoom setting, which drops off to a still considerable 100 degrees at 17mm.

Performance

Despite the conventional motor, autofocus is fast, if a little noisy. It's normally not an issue, because focusing will usually be in the tiny fraction of the range that covers 0.4m to infinity. Shots are often severely overexposed, but image quality is good and, considering that fisheye lenses usually capture a lot of sky, the Tokina's resistance to ghosting and flare is welcome.

Sharpness

Nice and sharp, especially for a fisheye. The Tokina manages to resolve plenty of detail right into the corners of the frame.

As you'd expect from a fisheye lens, distortion is off the scale. It's most pronounced at the 10mm end.

Image quality is pleasing, but you need to watch out for overexposure. Note that the fisheye design meant we could not test at focal lengths other than 17mm.
