I have been thinking about getting a wide or Ultra Wide lens and have been reading a lot about the Tokina 11-16 DXII f/2.8 and the Sigma 8-16mm f/4.5-5.6. If money were no object I'd probably buy a new Sigma. However, I have a possible opportunity to but the previous version of the Tokina 11-16 f/2.8. This is the DX, not the newer DXII. However, this used lens is in excellent condition and the asking price is only $350. I'm thinking this might be a good Ultra-Wide to start with and I could always sell it later and upgrade if I felt is won't doing all that I need. I know the newer version has better coatings and a better focus motor. Does anyone have experience with this lens and is $350 sound like a good deal?

For starters, there is no real advantage to the new version over the old version optically, according to lenstip.com. I have both this lens (version 1) and the Sigma 8-16. The Tokina lens is quite sharp, but it has two Achilles heels: work against the light and chromatic aberration. These were a big problem for me, and after I bought the Sigma I never again used the Tokina.
If you shoot against the light you need to be aware that the Tokina is trouble. It produces a lot of flare artifacts: not only a large comet and series of smaller ones, but large concentric rings in some situations that are basically impossible to edit out. Bright light sources also degrade the contrast quite noticeably, as can be seen below. I did an informal shoot at Asakusa Temple in Tokyo. The first shot is with the Tokina @ 11mm. Compare it to the next, the Sigma @ 11mm. Then have a look at the difference in FOV that those extra three millies give you, with the Sigma @ 8mm.
Both lenses suffer from some CA off axis, and more when defocused off axis, but the situation is quite a bit worse with the Tokina. Of course this can be cleaned up in post, but you can't get the sharpness back.
In terms of sharpness both lenses are very good in the center. The Sigma is definitely superior in the corners (at equivalent apertures), however this is probably not a big deal to most people. It is noticeable at 50% and above.
Mechanically both lenses are good. Tokina version 1 has no built in motor, so it is rather slow, but not really that much worse than the Sigma (if you have a camera that can handle it: do you?)
One advantage of the Sigma is that you can manual focus in AF mode. The focus mode on the Tokina v.1 is controlled by a clutch, and in AF mode no MF is possible. Also, the Sigma has a much closer minimum focusing distance than the Tokina.
On the plus side for the Tokina, it accepts filters, and has a fixed max aperture of f2.8.
If you can live with the limitations of the Tokina it is a very good lens, but if you intend to use your UWA against the light, you should really think twice about the Tokina. Please also read the reviews of those lenses at photozone.de and lenstip.com
