I've read the vignetting isn't too bad wide open, but obviously gets progressively worse as the lens is stopped down. I found some sample photos of it on a full frame... but have yet to find any on an APS-H. I'd love to get one of these for my 1DII FS: 85 1.8 w/hood - $300!!!

Kinda disappointed by the softness wide open mixed with the noticeable CA and although I didn't experience it myself when I used it (briefly) I've read it is very prone to flare. Samples of the sigma 30 wide-open on an APS-C body look pretty darn good. I tend to shoot at wider apertures more often than not, so I'd really love to see what kind of results the sigma would give me (in terms of vignetting) wide open through about f/5.6 FS: 85 1.8 w/hood - $300!!!

I'd appreciate it! FS: 85 1.8 w/hood - $300!!!

Still, I'd love to see some controlled shots at f/1.4, f/2.8, f/5.6, f/8 as a guideline. FS: 85 1.8 w/hood - $300!!!

I shot this with my 5Dii and cropped down to various sizes (also see the post above it). I think the Sigma 30mm makes a pretty nice lens for a 1.3x camera. "Raw" is not an acronym, abbreviation, nor a proper noun; thus, it should not be in capital letters.

But basically the breakdown is: f/1.4 through f/4 is useable. f/4 and slower; you start to see pure black corners. I guess you could crop a 1.5x image out of it still, so it is not useless. Taylor
