I took the lens out today and did some shooting with it. It renders out of focus backgrounds much nicer than the old 35F2. Blobs of light are circles in the background. The lens is sharp, with fast AF in most light. It slows a bit in very low light, but it is still fast.
There is a comparison of the bokeh on The-Digital-Picture.com and the new 35/2 IS definitely has the best bokeh of them all, although the light blobs from the old 35/2 aren't so bad either. They look very clean, but yeah, they're not round and round *is* better looking, no doubt about that.
The others all look awful I think, the 35L included.
