Hello fellow POTNers! I have a somewhat technical question about micro adjust. Well technical for me, might be common knowledge to some.

Basically i wanted to know how many cm or whatever the measurement is, that the plane of focus shift when u adjust +or- for MA. I dont if its possible to compute per click or for 5clicks.

The amount of actual adjustment per click depends on the focal length of the lens. Thus there is no relation you can use for all cases. They are all different.

It's always possible to calculate how much 1 click corresponds to, however, the value is definitely depends on the focus distance, for example, could be a couple of mm at macro distance, or a couple miles at infinity. So, it's almost pointless to do such calculation.
