Do you prefer using low, mid, or high apertures for focus stacking?

Your effective aperture (EA) is the magnification +1 times the lens aperture, so as said above diffraction can begin to degrade the IQ. Like most things it becomes tradeoff between DoF and Diffraction. I do lots of extreme stacking (sometimes ~600), mostly with microscope objectives for high magnifications, and the EA tends to hang around 18~20. These lenses don't have selectable apertures, so you get the EA the lenses was designed around.

Best,
