Leica SL camera firmware v1.10. OIS disabled.
Update 15 May 2016: firmware 2.0 fixes some bugs, improves focusing accuracy, and possibly may actually make compensation for focus shift work (that is biasing in a focus difference based on shooting aperture, which of course does not help if focusing manually wide open and then shooting stopped down).
Focus shift is an extremely difficult issue to deal with using a digital camera. It’s bad enough if autofocus cannot focus accurately and precisely (a common problem), but if the focus actually changes with stopping down, it’s a nightmare. Any rational person certainly expects perfection in a $13K camera system.
