Summary: I can go far and wide on this lens but let me stick to the facts. The camera is D40, had the lens for 1yr+ and we took over 200-300 pics with it. My 2 other lenses in the bag are 35/1.8 and 55-200 Nikkors. I'm shooting mostly outdoors with it - scenery, machines mostly, flowers, some candids + Sharpness - it's OK even at 12mm as long as you stop at f/5.6 or above.
Summary: I needed a good wide angle for a low price ( I know I'm taking a risk there) I'm a photo student and wanted to save a little money. But I feel like this lens is fickle in the sense that I have to have the right combination of shutter/fstop for it to work properly. Wide open and pulled back there is some distortion on the edges, up close and closed it's better. Not ideal for landscapes but maybe group shots.
Summary: I have never had such mixed feelings about a photography product. Overall, it's still the most-used lens in my arsenal of 5 lenses, but it has a flaw that drives me up the wall. It can't autofocus worth a damn. If I aim at something 15 feet away, it will usually focus at about 3-5 feet.
ATTENTION ALL FULL FRAME AND 1.3X CROP BODY USERS!!

Summary: I was seriously planning on buying this lens, but as is necessary with all 3rd party lenses, I had to do some research to find out if it fit on an EF mount. Save yourself the time of researching it (or if you want look it up on the forums), the answer is that there is sever vignetting between 12mm and 16-17mm on a 1dMK1, which has a 1.3x crop factor! I have not seen any test shots with the lens on a FF, but I can imagine it gets much worse...
Summary: I just returned my Tokina 12-24 lens today after owning it for about a week. I purchased it based on various reviews, including that of Rockwell. What changed my mind was a comparison with the Nikon 10-24. I may have purchased a lemon, but somehow I doubt it (unless Tokina has poor QC in their factory). Even without blowing up the images to peruse the detail, the Nikon simply looked brighter and sharper.
Summary: Ok, after 2 weeks of tweaking, I still could not get this lens to focus properly at 24mm with any amount of AF micro-adjustment on my 7D. It appeared that with a setting of +20 results were getting better, and from time to time, even acceptable, but the focusing at the 12mm end was then entirely thrown off. AF at 12mm is spot on, yielding tack sharp images every time. 24mm at wide open is on the soft side, even for objects that are in focus.
Summary: The Tokina 12-24 is very heavy, solid feeling wide-angle lens. Without doing any scientific testing, I was pleased with the IQ on some of the indoor shots. I ended up returning the lens, however because the level of flare and loss of contrast with a light source anywhere near being in frame was unacceptable for a lens I intended to use primarily outdoors. There is a newer version of this lens (don't know if it is available on Amazon yet) with different coatings.
Summary: I've used this lens for two years now. I am using it on a Canon 40D digital SLR. It is sharp but not as sharp as the Canon equivalent lens. It is very wide and works well for very wide dramatic shots but its focal length range isn't great enough to keep me from constantly wanting to switch lenses. The next lens up that I have is a Canon 28-135mm and I find myself constantly switching between them. The one real problem I have with it is that it is very heavy....
Summary: I got some great shots out of this, but quite a few "soft" shots. At larger apertures it is "soft" - need to go down to f8 for good edge to edge sharpness. I seriously wonder that I may have a one-off duff instance as other customers rate it well. Will check and update this review.
