Thank you guys, i'm really conscious about comparing
two different focal range lenses and that's not comparable,
But i'ts about image IQ, it's to have an idea of what delivers
as image quality, to have an idea of what to expect comparing my 16-35 II
Thank again
+1 to PWP, not good to compare these two lenses, very different uses and composition.
and I agree with Dylan regarding the image resolutions from both of these lenses.
I know these are two very different images but I hope they give you an idea how much sharper and more contrasty the new 24-70II compared to the 16-35II. Both images were sharpened for screen when uploaded by Lightroom, in low setting.

EF24-70II @ 24mm, f16 on a tripod and manually focussed using live view (one would think @f16 that diffraction will lower the resolution of this lens to the same level as 16-35 at f11)

It's a little difficult to see the difference on the monitor but I can definitely see the resolution difference when I printed both at 20x30. My copy of 16-35II, at 28-35mm, the edges are noticeably soft even stopped down to f5.6-f9, but it's decent at the wider end where I need that lens to be useable. I should add though that resolution is not the most important thing. There are just those scenes that you can only get with a UWA lens that you can't reproduce with a 24mm. So like Neuro said, there's a place for both these lenses in your kit. You need both until Canon graces us with an even better UWA lens.
