Re: 17 and 24mm TS-E lens profile?

The 17 TS-E has been my main lens for 10 years.  In ACR I always dial in +12 to +17 at default centering for vignetting.  I do a lot of shifting/stitching and I apply this to shifted and unshifted images.  If I am in a rush I just dial in +17.

There is extremely little CA.  I will check from time to time with backlit images and simply turn correction on.  Again, if I am processing a bunch of images I will simply turn it on anyway.  Rarely, if ever, do I need to dial in more strength.

Fully shifted images require at least one full stop extra exposure.  When shifting/stitching I balance the exposures of each frame so that the overlap areas closely match.  With some subjects Photoshop blends exposure easily with others you can see the border if the exposures were not matched.
