I suspect that the aperture is returned to f/2.8 after the first shot. Maybe do a trial an look into the lens what happens to the aperture. And then forget about the mess of taking stacks, they are not worth the hassle, especially if parts of the subject overlap within the stack, that will always lead to horrible artifacts that no software can remedy because they are down to the physical facts of focusing "through" foreground elements which will be depicted unsharp but larger as they are in the stack layer that is sharp...

Good call Charly,

I tried reducing the exposure by 2x in Lightroom and now the pics are identical, the formerly bright one with reduced DOF. So this is what is happening here.

Which is weird for 2 reasons.

1. It shouldn't happen in the first place

2. If it does, it should register as F2.8 in the EXIF data. But that says F5.6 still.

Well, I assume it will be removed when Canon releases the fixed firmware. We'll see.

Also, about the stacking: I found it to be practical for some cases. Sometimes, it works quite well without too much of a hassle if one isn't too perfectionist. Also, it can be good just to have a range of shots to choose from, so I like the functionality.

Especially since the high fps of the R6 in electronic shutter can do it very efficiently, the 40fps of the R6 Mk2 no doubt increasing this even more.
