Sigma 17-70mm f/2.8-4 DC Macro OS HSM Contemporary

I've seen the review here which mentions Chromatic Aberration / Purple Fringing being not too well-controlled, but try as I might, I am unable to make this lens produce significant visible evidence of CA . I'm testing it on an EOS 80D, shooting RAW, Adobe Color Space.

Convenient focal-length range for a go-to carry-everywhere lens; Excellent sharpness throughout, Well-controlled CA, Silky feel to the zoom ring, No front-element rotation during A/F, Looks great, Light and compact, but not too light

No manual-focus over-ride; Focus ring rotates during A/F

Phenomenal lens

I purchased this lens to replace my standard kit lens that was originally included when I purchased my camera. I can say that after testing the new lens that I am well impressed by the build quality and the resolution of the pictures that are sharp in colour and clarity.
