This aperture series looks at near-to-far performance with a very difficult scene to capture with much detail (depth of field). Accordingly, a 4-frame focus stacked image is included for comparison (using Zerene Stacker).
Series includes full resolution images from f/2.4 through f/16 at up to full resolution plus a 4-frame focus stack at f/11 to show just how limited depth of field is, even at f/16.
These aspen seem to be affected by some kind of disease which makes them weep from knots on the trunk. It might be drought stress from some very dry years.
