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.
