Yes, Tokina...well made lenses, use it for tight corporate jet lavs and sometimes cockpits...Sigmas OK but my experience has the Tokina some of the most underated optics going & and well priced...next best thing to OEM Nikon.

I use a Sigma 10-20mm and love it. I've 100's of photos taken with it on the database. Just ensure you test it if you get one as there have been issues with upper-left corner sharpness (mine was replaced free of charge as it suffered the problem), other than that, it's a great lens. Which version to go far is up to you, whether you need the wider aperture or not.
Equipment: 2x Canon EOS 50D; Sigma 10-20 EX DC HSM, 50-500 EX APO DG, Canon 24-105 f/4 L, Speedlite 430EX
Most lenses have some vingetting to a degree. At f/8, it's hardly noticeable and by f/10, it's disappeared. You can remove it in Photoshop if needed, but unless you have a uniform sky where it becomes noticeable, it's not required.
Quoting BriceJohnson (Reply 6): Could I produce un-edited images with this lens that could be submitted and accepted onto A.net, at 10mm?
You know what a.net is like, they require minor tweaks at least. Editing with this lens is no different to any other lens you have.
I can't compare it to the Tokina as I've never used one, but I'm more than happy with my Sigma 10-20. I've been using one for 5 years now and have only good things to say about it. A few recent examples;
