I began dabbling with it lately and - inspired by this comment - I though about diving deep in this topic and try to understand this function that works in a pretty cryptic way. Canon documentation says: trial and error -.-

The main questions are:

• how many steps do I need?
• how wide should each step be?
• is in-camera stacking any good?

I used it a couple of times with my R6II and never got anything deleted when the in-camera stacking gave an error: it created a final JPEG with only a selection of the stack pictures (this behavior is very good I recon) and didn’t delete anything- maybe on tbe R10 it works differently?

I got a very nice JPEG out of one of my first tries, but I couldn’t say I learned how to do it consistently:

My aim is to set up a small guide with some tips and reference values (ideally find out the correlation between aperture value, focal length, focus distance and the resulting step size): do you have any hints, failure or success stories? Let’s discuss :)
