Turn off the illumination correction on your RP. The lens is fine... Just Canon's firmware messing up. The 6D you mention probably is a 6D mark II?
Dave, it is the same issue often reported with particular Sigma lenses on Canon cameras. Illumination correction going haywire with lenses the camera "misunderstands". Nothing in the lens is wrong or "going on".

If you look at the bottom right corner, you can actually see a lighter circle on the inner edge the dark corner circle.
Same as here:

Same lens (Tokina 16-28mm), same setting (16mm), same camera (RP), same issue (illumination correction turned on).
