Yes! Focus Bracketing is one of my very favorite features!

I've been using it on my M6ii for over a year now, for all kinds of stuff.

Have fun thinking up all kinds of cool uses for it!

What is the effective difference between focus bracketing and simply using a smaller aperture? Thanks!

The smaller the aperture, the lower the lens resolution due to diffraction: https://www.kenrockwell.com/tech/diffraction.htm

My test was at f11 and even that was bad, I should've stayed at f8 ( my lens is f 7.1 at this zoom level).

So basically you can shoot with optimum aperture for your lens resolution-wise (say f4 for fixed f2.8 prime lens) but DOF would be very thin, hence focus stacking fixes a problem.
