Isn’t that what we’re all here for? :-)

But as you note, it only works with certain lenses, of which I have none that
qualify. (Well, I have the 7-14, but as you mentioned with the fisheye, I can’t
really see stacketing to be useful with it.)
My goal (besides having fun) is
1) to support my stable of OM-System macro glass, and
2) to make the process as fast as possible, to avoid lighting changes, wind,
etc.
What I REALLY want is for the camera to tell me when it’s ready for another
shot. I suspect it’s Pretty Damn Quick, but don’t want to over-run it.
Unfortunately, I have not been able to find an API to look at the USB port as
see when the camera is ready for another shot. So I’ll have to use the 2.5mm
exposure control plug, and use an arbitrary wait period to make sure I’m not
over-shooting the camera.
The stepper motor should be able to move 0.005mm and settle vibrations within a
few milliseconds. I suspect the camera will be done with whatever it is doing
by then.
