I do a lot of focus bracketed work. The biggest problem you all will have depending on your lens is focus breathing. As the focus distance changes, some lens tend to appear to zoom (including primes). Also as the focal point moves further away nearby objects such as tree branches etc. bloom and tend to cover areas you don't want them too. Using Helicon Focus to process the RAW images one can do some correction of this blooming. With the in camera processing I doubt the camera's firmware can make those kind of adjustments.

This is an focus stacked image shot bracketed with Canon R5, Canon 70-200mm lens at 200mm, f/11, 1/125th sec. exposure, ISO 400. It is made up of 878 Focus Bracketed images processed to yield 114 individual Focus Stacked images, 6 rows x 19 columns 30% overlap in portrait orientation.

The original image is: 2.278 Gaga-pixels, 32,282 x 70,569 pixels, 107" x 235" 300 PPI https://abbascreationsphotography.com/GC_Moonrise.htm

Impressive image John and looks a complex job.

May I ask what is a Gaga-pixel? Is it a typo or something I should understand?
