Sony 12-24mm f/4 G @ 24mm: Single Frame Performance at f/11 vs Focus Stacking at f/11 (Downed Tree, Last Kiss of Sunlight)

See my Sony mirrorless wish list.

Focus stacking using Zerene Stacker. See my tutorial/how-to in Making Sharp Images.

This 3-frame focus stack compares what is possible with a single frame at f/11 to a focus stack at f/11 using 3 frames. The difference in total sharpness is remarkable, especially since f/11 at 24mm might be expected to have good depth of field. As the single frame shows, no single frame is up to the job for an image like this.

Includes images up to full resolution. Also includes crops showing the stacked result versus , close/medium/far focus distance frames.
