Hyperfocal Distance
Use hyperfocal distance to maximize depth of field.
When focusing at hyperfocal distance (H) from lens, depth of field or range in acceptable focus extends from distance H/2 through infinity.
Smaller apertures & shorter focal lengths have closer hyperfocal distance.
When photographing landscapes, instead of focusing on a distant subject, focus at hyperfocal distance or slightly beyond to maximize depth of field.
Overshooting hyperfocal distance while focusing has minimal effect on DoF, but undershooting can have drastic impact, so it is best to be conservative and focus longer than H.
To achieve focus at hyperfocal distance, set lens to manual focus, look for distant object, turn focusing ring to infinity, then turn back focusing ring until the distant object just goes out of focus. And at that instant, rotate the ring just a bit towards infinity focus.
