The speed of autofocus can now be set (and it's incorrectly labelled as sensitivity instead of speed), however it only seems to apply when autofocussing from one subject to another, and not when switching between manual focus and auto, or with the AMF mode, where it quickly snaps back to the subject still after making temporary manual adjustments.  When using the focus motor, it causes faster movement than then lens will allow, and this means slippage on the gears.  After each slippage, the lens needs to be recalibrated, making auto focus on manual lenses generally impractical.

Has anyone else found this, or a workaround for this problem?
