This series from f/4 to f/8 looks at sharpness across the field for the Fujifilm GF 20-35mm f/4 R WR at 21mm on a finely detailed landscape scene.
With a 6-frame focus stack at f/8 to show the imaging limits of the lens.
Fujifilm GF 20-35mm f/4 Aperture Series @ 21mm: Icebergs in Dana Lake, View to Mt Dana
Includes images up to full camera resolution.
You really have to see this image on a 6K display to appreciate the stunning level of detail—wow! But my budget is tight right now and I have to send the Dell 6K back in a few days and boy am I going to miss it.
