I did a little step focus experiment today.
What I tried to do was get 20 images using my FLASH... didn't work. You can tell the camera how often to shoot and the time delay (enough to recharge a flash), but the flash doesn't fire from the hot shoe!! That SUCKS!
So, it was 20 images and then stacked in HeliconFocus. A very cool software package I bought on sale over the weekend.
First image, just a single shot.....

Second image, below, a 20 image stack using HeliconFocus. And, I did a little PP on it so that is why it looks a little different from the first image above.

Images are shot with a Nikon D850 set on the Focus Step feature.
the Nikkor 105mm f2.8G set at f8 for all images.
I error I noticed I made, I didn't start the focus on the closest edge of the coins to the camera. So, it is ever so slightly out of focus.
What a very cool and very good software package!
