seriously have a look at the sigma 85 f1.4
at f2 to f2.8 it is super sharp, blows away even the 70-200 mk2
"Blows away"? Wombat, you been smoking powdered KR rolled in DxOMark papers again? 
I'd say the Sigma 85/1.4 at f/2.8-4 is pretty similar to the 70-200 II at similar apertures, sharper in the center, not as sharp away from the center.
Still, 'similar to the 70-200 II' is high praise for any lens, especially one costing what the Sigma 85/1.4 costs. Definitely worth a look...
I have 2 copys of the 70-200 f2.8L IS II and my sigma 85 f1.4 @ f2 is noticably sharper than either L @85mm and wide open at f2.8 AND thats a whole stop faster.
I'm not saying the L zooms are bad in any way they are fantastic however the sigma 85 is really THAT good
well my copy is anyway after i got it back from sigma after they recalibrated it due to it being heavily front focusing out of the box. I guess this speaks to the questionable QA QC of sigma however they fixed the problem quickly. also the build and manual focus of the sigma is superior to the canon non L lenses
obviously the build of the L lenses is superior in every way though
I AM talking center sharpness here since really at such wide apertures typically the corners and edges are blurred into oblivion due to DoF so largely irrelevent for the shooting of portraits with this lens.
Bang for buck this lens is unbeatable IMO
I really hope their annonced 35 f1.4 is as good!
