45-megapixel Nikon D850
Zeiss Milvus 25mm f/1.4

Examples: Focus Stacking in Yosemite High Country and White Mountains

Examples in the Eastern Sierra.

Many of these examples use focus stacking (Zerene Stacker) to deliver far more detail than is otherwise possible, even at f/11. Focus stacking is the only method by which adequate depth of field can be obtained in such scenes (while retaining strong contrast), f/11 being inadequate and f/16 far too damaging to contrast at all levels, from diffraction.

The Zeiss Milvus 25mm f/1.4 is ideally suited to focus stacking, with outstanding control of color aberrations, an f/1.4 aperture to nail the focus where desired for precision stacking, and a low level of breathing (change in focal length with focusing). Its 24mm focal length at f/9 - f/11 means that many scenes require only two frames for stacking.
