Hi there, when i setup a rack focus on my 550d with build magiclantern-2011Feb15.550d.fw109.AudioMon.follow-focus-2.alex and try to let it run it mostly does not work as designed. for example i focus from near to far like 10 steps and when i let it run it only goes 6 steps. backwards it does for example only 4. again forward it makes 8 steps. so it has its own mind. the change between near and far seems to be correct but the amount of steps is almost everytime wrong. sometimes i have to restart my cam because it stopped doing anything with the AF. the feature is one of the best if it will work fine :) keep up the good work.
Issue #364 resolved
