If anyone is interested, just finished comparing the new Sigma 135-400 F4.5-5.6 DG lens against the Canon EF70-200mm F2.8L IS lens. We used a 1D Mk II and took shots only at F8 at focal lengths of 135, 200, then added a 2x on the 70-200 and did one at 300 and a last at 400. All shots were with camera on tripod. Viewed the raw files on PS. Expected to see the Sigma fair poorly but it did VERY well. This was a surprise to all of use. At $599, if you can live without IS, it's a bargain for digital that I would feel good to recommend. Plus its smaller and is well built (metal not plastic). AF is not fast like USM but at $599 street price not something I would worry about unless you are shooting NASCAR.
It does not make much sense comparing tele lenses at F8. The Canon delivers excellent results at F2.8, die Sigma has 4.5 or 5.0 in the comparable lengths (which is rather slow). It is difficult to optimize lenses for open aparture, so testing the Sigma at 4.5 or 5.0 would have been more interesting than stopped down. Furthermore, shoothing tele you mostly lack speed (think of moving subjects) or want a nice blur. Tele lenses stopped down - well yes, sometimes but I do not believe this is the general case.
