Fujifilm GFX100S: Focus Accuracy and Precision with Fujifilm GF 50mm f/3.5

re: precision and accuracy
re: focusing accuracy
re: Fujifilm GFX100S

See my prior post on this matter, which prompted this controlled test: Autofocus Accuracy: Fujifilm GFX100S + Fujifilm GF 35-70mm f/4.5-5.6.

Confirming the results shown with the Fujifilm GF 35-70mm f/4.5-5.6, this page does the same assessment with the Fujifilm GF 50mm f/3.5. Using two GFX100 camera bodies.

Fujifilm GFX100S: Focus Accuracy and Precision with Fujifilm GF 50mm f/3.5

Includes 34 frames plus frames from two cameras plus manual-focus reference frames, discussion, along with troubleshooting and mitigation advice.

Very interesting to me is that shooting outdoors today, I observed the variance firsthan and in real time in magnified Live View, using the procedure I outline.
