I just received the new Sigma 10-20 F3.5 for my 50D.I had tried the Canon 10-22 earlier, but sent it back. Build quality is much better than Canon 10-22. From my initial few interior shots, lack of distortion is excellent, even better than the Canon.
Has anyone had the opportunity yet to test thislens' performance ?
Has anyone tried it on a FF ?
Thanks
First off, congrats on your new piece of glass.
I have only used the earlier version of 10-22(4-5.6 HSM), mostlywith f-stops between f5.6 and f11,and was very pleased with it. I'd expect improvement from this new one.
I don't think this lens is intended for useon a FF body, though.
Good luck.

TheSigma 10-20mm f/3.5 is the only other lens I'm considering in the Tokina's place. I'd really appreciate some good samples, and maybe a note in the caption telling what exactly you were focusing on in theframe.
Sean,
Why are you not considering the EF-S 10-22mm f/3.5-4.5?Is it the price? A refurbished copyiscurrently available at Adorama for $629.95.
I considered it, but to be honest I simply don't like variable-aperture lenses. I've read nothing but good reviews on it...if it was an EF-S 10-22mm f/3.5, I'd buy it in a heartbeat.
I hate variable apertures too but I think it has a lot to do with my OCD [:D]. I wouldn't mind if it were a constant f/4. Either way though, it's a fantastic lens and for most of what I am doing with it the aperture usually gets set to f/8.
Sean - I will do microfocus adjustment (if needed) and post some pictures later this week. The only pictures I took to date were to test flair - these two pictures had the morning sun barely in the top corners of the frame - I do have a b+w mrc uv filter on.

Here's another quick snap I took this morning - sun at my back - all three shots f6.7 10mm[img]/cfs-file.ashx/__key/CommunityServer.Components.UserFiles/00.00.00.29.52/10_2D00_20-Test_2D00_5_2D00_3.jpg[/img]
Let us know how it works out. I've been using the old version for the past couple of years and its been awesome. While there is some distortion, it is VERY sharp. The only issue I have against the new version is the larger filters... I prefer the originals 77mm threads as that isthe filter sizemost of my other lenses use.
