Just remember, that if its a modern lens with an infinitely rotating focus ring, then the auto calibrate function won't work, as there is nothing for the motor to detect. If its a normal slr lens with hard stops on the focus rings, the stronger motors may well damage them anyway, so it may be best to manually calibrate if possible.
Just bear in mind, that these newer lenses which have infinite focus rings never behave well with remotes. It seems that the numbers in the little window turn at a different rate to the focus ring, so it looks to me like the two rings are not directly connected. If you do a fast focus move, the two rings slip away from each other, and your marks move, so it is quite difficult to repeat marks, just make sure you keep your focus moves slow, and check often because it will slip out eventually.
These lenses were never designed to be focused accurately with the ring like this, they are primarily designed as auto focus lenses, but have that ring on the outside so you can adopt the 'Twist it til' its sharp' approach if you wan't to.
Hope this helps,
