The 90 AA has little focus shift but when using the rf the cam on many lenses does not follow the focus properly. Lenses that focus accurately at infinity can be off at 10m and then on again at 3m all at the same aperture. Henning described it here: http://leica-users.org/v49/msg10637.html. I mistook it for focus shift when I first got my M8.
