My 17-50 Tamron exhibits a fair amount of CA at the long end. Much more than my Canon 50mm 1.4.
However, Canon DPP along with every freeware RAW program I've tried (Gimp / RAW Therapee, etc) do a terrible job with CA. You get what you pay for.
That's because DPP corrects for (most) Canon lenses based on a lens identifier number.
3rd party lenses are not supported; those lenses use a LensId number of existing Canon lenses.
