Fujifilm GF 50mm f/3.5 Aperture Series: Deck Planks (massive focus shift)

I had forgotten just how severe focus shift is with the Fujifilm GF 50mm f/3.5 at close range—about the worst I have ever documented, but only at close range.
As it bit me when making some tests, I decided to document it with another subject entirely different from the first two:
Fujifilm GF 50mm f/3.5 Aperture Series: Deck Planks
Includes images up to full camera resolution from f/3.5 to f/22.
Fujifilm GF 50mm f/3.5 Aperture Series: Mining Cabin Interior
Fujifilm GF 50mm f/3.5 Aperture Series: Burned Pine Among Boulders
The behavior shown in these series is critical to understand for those looking for the best possible results from the Fujifilm GF 50mm f/3.5 at close range.
I feel increasingly disappointed with Fujifilm GF glass because focus shift this strong means that the risk of sub-optimal results rises dramatically. Undue time-wasting care is required when focusing to compensate for the focus shift, but with autofocus it’s a total disaster since the Fujifilm GFX100S/100 focuses wide open with no feature to compensate for focus shift (at least not that I know of). And its variability and accuracy are marginal to begin with. So I again point to my recent essay on real-world capture resolution vs lower resolution cameras like the Sony A1.
