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.

See also Flowers Amid Bristlecones, which used the Sony 16-35mm f/2.8 GM.

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.

Sony 12-24mm f/4 G: Imaging Performance @ 24mm, Single Frame vs Stacked: Downed Tree, Last Kiss of Sunlight

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

Focus stacking is a tool that should be mastered by any serious landscape photographers for any scene like this one, since depth of field can never be adequate for this extreme near-far composition. Focus stacking helps overcome three issues:
