Good wide angle choice for 7D that is 'affordable'

[richmond virginia wedding]

<p>I have a Tokina 11-16 F2.8 that I purchased back when I was using the 40D. It is an excellent performer optically and built like a tank. I can confirm that it does work well as a 15-16mm prime on my 5D mk2.</p>

<p>Brandon -- you ought not be using such a signature, unless you're a paid advertiser (or paid subscriber).</p>

<p>Someone above wrote the 10-22 is fast, not really -- it's a variable aperture, widest is f/3.5. (maybe they meant it's responsive, quick to find focus?). The 10-22 would be the only EF-S lens though I'd keep were it given to me. ;-)</p>

<p>I acknowledge that I often do overlook the Tokina 11-16, perhaps because my sources (the B&H catalog) indicate that it is digital only? Is its use on the 5D only at the 15-16mm focal lengths? Not much zoom there.</p>

<p>The Sigma 10-20 also <em>seems</em> to work on a "full-frame" if you only look through the viewfinder. When you look at the full image, though, there is vignetting even at 20mm. On a 7D you would see this in the new 100% viewfinder, I suppose.</p>

<p>The Sigma 12-24 works on the 5D as a 12mm to 24mm lens with no cutting off of the image at the wider focal lengths, as I understand it. It is about $100 more.</p>
