What I’ve never seen, however, is a focus-by-wire system that compares with the focus experience of a well-executed manual focus lens. At its best, it is still an emulation of true mechanical manual focus and still has some of those limitations, though with better feel and no input lag.
It often lacks “repeatability”, as there are no clearly defined focus points that you can prefocus to or quickly return to as a frame of reference, and the focus ring can spin indefinitely without any hard stops at either extreme. At its worst, it is a numb experience with lag between input on the focus ring and the actual movement of the elements by the focus motors.
Typically mirrorless lenses employ a “focus-by-wire” manual focus system where input from the focus ring is routed through the focus motor(s).
