This is to be expected, as such lenses aren't meant for video or reproduction work. Even with some of Canon's L prime lenses, I've seen colour shifts when stopping down... but I've only noticed this when shooting in infrared.

Good to note. But want to be clear that this was observed strictly during focusing, with no other physical adjustments or changes to aperture or focal length. Kind of a nightmare for video.
