How it works
Sharpness is a zone, not a line.
Aperture
Smaller opening, deeper zone.
Going from f/2.8 to f/8 roughly triples the depth. A wide aperture isolates a subject, and a narrow one keeps a whole landscape sharp.
Distance
Further away, deeper zone.
Depth grows quickly as you move back. Focus on something close and the sharp zone can be a few millimetres thick.
Hyperfocal
The sweet spot for landscapes.
Focus at the hyperfocal distance and everything from half that distance to infinity looks sharp. It is the standard trick for landscapes and street work.
Using the equivalent focal length.Enter the real focal length printed on the lens, not the 35 mm equivalent. The camera format setting handles the sensor size.
Treating the limits as exact.Sharpness fades gradually. The numbers assume a standard print size viewed at normal distance, so a large print or heavy crop needs a stricter margin.
Stopping down too far.Past about f/11 on most lenses, diffraction softens the whole picture, which can cost more than the extra depth gives.
