See my Sony mirrorless wish list at B&H Photo.
Making an image like this has always been frustrating with a lens in the 85mm range (well, impossible): there is no way using a single frame to obtain a sharp foreground and subject and background. So it has always been a choice of how much blur to allow, and for what desired effect.
The use of f/11 is just sufficient for sharp foreground grass with the rear of the boulder starting to blur slightly. A second f/11 frame is thus needed if sharpness is desired on the beaver pond area and the far background.
Stacking notes and annotated focus placement are included as instructional notes.
