Hiii....

Just want to find out from users of this lens & other wide angles. How do u find it so far? I'm referring more to the sharpness/contrast produced by this lens.

I saw the MTF chart of the lens and it doesn't seem to perform as well as the 16-35. As a comparison, I also checked out the 20-35mm and 20 mm f/2.8 prime. Hey, if I read the graph correctly, the 20-35mm is better than even the 20mm prime or 17-40mm L at the wide end! How come?! Shouldn't primes and L lenses be better in resolution? It also performs quite decently at 35mm.
