I used a 'racing champions 1:144 scale dragster with decals and white lettered tires and can read the tiny letters now with raspicam. dont turn lens more than 1 rev either direction as threads are very short and hard to screw back on if removed.

But can I ask you a question?
If I adjust the focus at the center of the plane of rotation, the scan improves?

Well...  Not exactly.

The Raspicam lens is glued in place.  You first have to break the glue joint, then you'll be able to refocus the lens.  It can be done either by using a fine x-Acto knife to remove the glue, or by gently turning the lens until the glue joint breaks.  Be careful when you do this, not to put too much pressure or you could tear the camera body off the PCB.  Best to hold the camera body with a pair of needle-nose pliers while you're twisting the lens.

Many of us have done this already, and it's doable with a little patience.  Once the lens is free to turn, you could add the lever posted above, but most likely it won't be needed once you adjusted the focus the focus

If yo have access to a printer you can print https://www.thingiverse.com/thing:211641 and attach to the cam.
