Fujifilm GF 20-35mm f/4: Evaluating Lens Performance and Potential via Focus Stacking

re: Fujifilm GFX100S and Fujifilm GF 20-35mm f/4

Aperture series are very good at showing lens performance across the aperture range, but depth of field is typically limited even at f/11, so that often peak potential in some parts of the frame cannot be understood in that series.

Here on this page, focus stacking examples are shown. These are practical and actionable demonstrations of what the lens can deliver across the frame when depth of field is full-range. And practical in terms of real-world photography: what the lens can actually deliver on that demanding 100-megapixel sensor using appropriate technique.

Fujifilm GF 20-35mm f/4 Examples: Examples: Focus Stacking (GFX100S)

Includes images up to full camera resolution, corrected for distortion and not, and single shot vs focus stacking—4-way comparison of each image.
