Fujifilm GFX Focusing Precision and Aperture Series with 63/2.8: View to Mt Whitney From Alabama Hills
Like the Cerro Gordo Church series, this series shows the problematic focusing imprecision that plagues the Fujifilm GFX, with all its lenses (32-64mm, 63mm, 120mm). I don’t expect behavior to be any different with the 23/4 and 110/2, but I am curious to see if it is better or worse with the 110/2 since there is razor thin depth of field at f/2 at 110mm.
The variability shown here was observed over and over in the field, a great source of aggravation because it becomes hit-and-miss to obtain optimal results. The greatest errors occur at distance where focusing precision is at its worst, and where tiny changes in focus can make a big difference.

I feel it is important to show at least two examples of misbehavior when I find it. For example, I showed a dozen or so examples of the Hasselblad X1D focusing issue, one which Hasselblad has acknowledged and is working on. Hasselblad has also promised me an X1D and lenses for re-testing when the time comes. So kudos to Hasselblad—I can’t ask for more than that (fix and take a fresh look).
BTW, I still have not heard a peep from Fujifilm. I never believed the original GFX problem diagnosis, now disproven as a theory given the same misbehaviors proven with a 2nd brand-new GFX and 120/4.
