Fujifilm GF 63mm f/2.8 R WR

Aperture Series: View to Mt Whitney From Alabama Hills (Focus Variability)

Not repeated here: see the discussion of precision and accuracy in the Cerro Gordo Church series.

This series assesses the Fujifilm GF 63mm f/2.8 at distance. Like the Cerro Gordo Church series, it shows the problematic lack of focusing precision that one can expect from the Fujifilm GFX.

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.
