Ok...so now we can compared the lenses on the same body:

35A vs 35L II on the 1DsIII @f/1.4

35A vs 35L II on the 1DsIII @ f/2

Vignetting appears to be about the same, but the resolution of the 35 L II is outstanding.

A quick comparison to two bench mark lenses (comparing wide open):

200 f/2

300 f/2.8 II

Resolution is similar. The 35 L II has more vignetting, but, it is f/1.4.
