Thanks for taking the time to explain the focus stacking functionality.
I thought I understood how it works but right now I’m not so sure. I THOUGHT I’d put in the # of steps, and the step size and it would do the calculation of how much of a change is required for the focus. But it doesn’t seem to work like that. To get a really deep focus I’d have had to put in 100 instead of 50. That’s a lot of images to record even with an electronic shutter and no delay.
So I’m still learning.
The Fujifilm X-T3 & 4 also have focus bracketing.
The color profiles are quite interesting. The ACROS for monochrome looks really interesting. I guess Fuji supplies them to Adobe who incorporate them into Lightroom? It’s a fascinating capability.

That seems to be a trend for the handling of this camera by Adobe - they must have been needing more vibrancy or something.
