Magic Lantern - DOF and Focus stacking demo

The Magic Lantern firmware for the Canon 5D Mark II adds the ability to display depth of field information, including hyperfocal distance, for lenses that report distance information. Most genuine Canon lenses do so, and all L series lenses report fairly accurate distance measurements.

The firmware also adds a "focus stacking" exposure mode that takes a configurable number of exposures with pre-programmed focus distance steps between them.
