This aperture series at medium distance shows performance from f/4 through f/11.
It also includes a 2-frame focus stack at f/9, which is interesting to compare to both f/9 and f/11. Depth of field is a major limitation of medium format, hence focus stacking is even more useful than with 35mm format. A 2-frame stack is easy and fast to shoot for a scene like this.
Includes image sizes up to full resolution from f/4 through f/11.
