Re: Dropoff seems like a greater problem to me...

Yes, I'm talking about lens distortion not focal length effects.

DXO would profile the lens themselves and if available (it is for the 12-35) use that information, ignoring the much simpler data in the Raw file, they would also do selective sharpening based on the local lens sharpness. BTW they have different profiles for OOC JPEGs (which they can also handle) and Raw files, for kinda obvious reasons. (Although I would only feed it a JPEG if a Raw wasn't available and I had a problem - perhaps when I start doing time-lapses, but not to date.)

P.S. I must, as a matter of some urgency, see which FoV (JPEG or DXO processed Raw) agrees with the viewfinder. I'm assuming the former. It's quite a significant difference, both images are 4608 wide, but if I crop the DXO one to the FoV of the JPEG it ends up losing about 150 pixels from each side!
