you may have a look at this rough comparison between Sigma 8/4.0
(old one) and my Tokina as well:
Images taken with ISO 200, 0,8 sec, aperture 8 on a 20D. The Tokina
crops are taken from a panorama which has been downsized from ca.
5000x10000 to 3500x7000 to meet the dimensions of the Sigma.
Unfortuneately the weather here around was bad the last 6 weeks, so
I was not really able to test the lens in direct sunshine. This
would reveal a bit of its behavior regarding CA and lens flare,
which is not as good as the Nikon 10.5 I'm afraid.
P.S. Sorry if this post should arrive twice. I sent it some hours
ago by clicking on "reply to list" but checking online now it does
not seem to show up anyhow.
