Impressions: the new Canon 16-35 f/4 lens is head and shoulders better than my old 16-35 f/2.8 version 1. The centers of all three lenses are similar at f/4, but the corners of the new 16-35 f/4 are just phenomenal! Sharpness, resolution, color fringing, resistance to flare make the old 16-35 look sick and are frankly better than my fabulously expensive 24-70 f/2.8L II, which is kinda depressing.

thanks for reporting! Yes, the new 4/16-35 is so much better than the old f/2.8 version (or the 4/17-40). But compared to the 2.8/24-70 I'm not so sure, seems to me that the 24-70 has sharper details except maybe in the extreme corners. But my impression might be skewed because the focus plane for the two lenses is slightly different, and there is a difference in contrast or exposure (flare resistance, vignetting?).

Yeah, I was surprised at that, too. Perhaps if I do a microadjustment with my 5D III I'll get a slightly different result with the 24-70 f/2.8L II. Frankly, I was shocked and maybe a bit depressed that the relatively inexpensive 16-35L f/4 IS appeared as good or even a little better in the corners. I mean, WOW! This is a seriously impressive bargain, 'cause I love the heck out of my 24-70.
