Has anyone tried the D850 capability of focus shifting with extension tubes? If so what make of extension tubes works, and any difficulties with them? Finally, did you use flash, and how well did that work? Was the flash able to keep up with the stacking exposures?

I just got my D850, and the combination of the built in focus shifting capability and the incredible resolution of the sensor has me very curious.

Thank you in advance for your advice, John
