Way behind in what way? The distortion on the 35/1.4 is a little high but that can be fixed in the computer. Bokeh is also a little odd sometimes but overall it performs very well:
And it doubles are a low light lens for close up shots. Very flexible.
As for other Canon wide primes, the 17 TS-E is simply awesome. Sharp corner to corner more or less to pixel level except under extreme shift. And almost no distortion. Acts more like a symmetrical view camera wide angle than a retrofocus SLR lens. "Good" doesn't even begin to describe it:
And I heard the 24 TS-E is very similar as well.
Sadly just like the rest of their newer pro lenses, it will be priced out of this world if it does happen.....
