Fujifilm GF 45-100mm f/4 Aperture Series @ 56mm: Alabama Hills Desert Wash, Sunrise View To Mt Whitney (Fujifilm GFX100)
This series from f/4 to f/11 was shot in the Alabama Hills near Mt Whitney. It examines field curvature and focus shift along with sharpness near to far and across the frame and unfortunately—lens skew / optical asymmetry.
Includes images up to full camera resolution along with large crops, all from f/4 to f/11.
Please also see the related image @ 80mm on the Alabama Hills examples page, which demomstrates the same lens skew issue seen at 56mm in this series.
