I am glad that 24-70 II L LR profile worked for you well. Glad to be at least of some assistance
attached is the print screen of the image 14 out of 50, DPReview. link to the gallery can be found in my post above.
24-70 II L is nowhere near as bad CA wise at F4, and you can detect CA in Sigma lens even at F8 and that is a shocker.
I love my Sigma Art and Sports lenses but this new 24-70 is a flop. I am sorry to call it out as it is.

JayS_CT said:I'm just not seeing that kind of level of CA (other the Sea Plane shot) in the ones you are considering very bad. Perhaps you can crop down to the specific area in some of the others (1:1) to show what and where you're seeing the severe CA?
I'm not here to defend a lens that I don't even have yet, but the full production lens' are out yet (to my knowledge). Sigma's also have the ability to be upgraded (via the dock - don't know how/if CA could be countered) and the IS is a nice to have feature that I TRULY wish Canon had considered in the MK II (otherwise a refurb' MK II would be in my kit already).
I am very interested in where you are specifically seeing the level of CA you're pointing out.

P.S. I also tried the Canon 24-70 2.8II profile and you're right.. better than the existing Sigma one... Adobe has some work to do.

It does clear CA for me very well. Vignetting is not an issue. CA levels are excessive comparing to Canon 24-70 lens performance in that department. I am not unique in finding the CA level of the lens to be excessive. There are many others who of the same opinion.
Please see lensRentals (not so favourable) review of this lens as well. I am happy that you find the lens performance adequate for your requirements and hope that the lens will serve you well for many years to come.
ps. DXO Optics Pro detects the lens as Canon 24-70 II L and applies lens profile correction automatically with a descent results.

I'm on the latest LR6 Beta and using the older SIGMA 24-70 camera profile, vignetting at 2.8 clears up very nicely, as does flattening the image field. Turning CA adjustments on/off isn't showing much of a difference at all...
