Thoughts... why? It still won’t work better than the branded one on the knee - after all, there are precise mechanics, and manual ones were not originally conceived for torsion by a motor - it will just turn out to be a perversion IMHO.
Well, so that he just gave an autofocus signal - they already said about the dandelion.

"Dandelion" to attach to it and flash it is not an option? To be honest, I haven't heard of any other way.

Sometimes factory lenses cannot get into focus, and this is with ultrasonic motors and other gadgets, but here we are talking about self-made ones. I want to play around - sculpt a controller (but only on Arduino))), a dandelion, a gearbox, a servo (although I think a regular motor can work) and tell us what happened!

I thought if you put "Dandelion" you can get the exact position of the sharpness setting and give the "stop" command to the motor. Or it is possible to find spare parts from another lens with similar characteristics and file method ...

it won’t work - by inserting something thick between the lens and the mount, you increase the working distance and lose aiming at infinity - in fact, you put an extension ring for macro photography) in the example above about Nikon there is a teleconverter, also an option, but there are probably problems with focus speed and sharpness )
it is difficult to turn the focus ring itself, because they are tight)
