P.S. the profile from DxO seems to work exceptionally well. I applied it to my test shots and the 16-35 f/4 IS comes out quite a bit sharper than the corrected 24-70 f/2.8 II photos! That seems crazy but is what I'm seeing. I'll have to play with it some more this weekend and do some more side-by-side photos, assuming the weather cooperates.
That's really odd -- your lens profile is affecting it's sharpness?
In ACR, profiles in there are for lens corrections
: vignetting, distortion, chromatic adjustments, etc. but not for sharpness. You'd never want an apply-to-all-shots-from-this-lens
sort of change to something that would vary for reasons other
than the lens. In other words, I ratchet my sharpening up or down based on the light I had and the resulting ISO I had to use. Do why is the DXO profile bundling sharpness with the usual lens corrections?
Please forgive my ignorance. I've always been an ACR guy and did not know this about DXO's tools.
