Focus & Depth of Field

The range of distances in front of and behind the plane of focus that appears acceptably sharp in the final image.

DoF ≈ 2u²Nc / f² m

Cameras, Formats & Systems

A control that stops the lens down to the working aperture so the actual depth of field can be seen before exposure.

Focus & Depth of Field

Markings on a lens barrel showing the near and far limits of sharpness for each aperture at the set focus distance.

m / ft

Focus & Depth of Field

A wide zone of sharpness in which foreground, subject and background all hold detail.

m

Focus & Depth of Field

The tolerance in sensor position, on the camera side of the lens, within which the image stays acceptably sharp.

≈ 2Nc µm

Optics, Lenses & Filters

The aperture beyond which diffraction, rather than lens design or sensor resolution, becomes the factor limiting sharpness.

N_limit ≈ pixel pitch / 1.22λ f-stops

Optics, Lenses & Filters

The spreading of light waves as they pass the edge of an aperture, which softens the image at small f-numbers.

d = 2.44 × λ × N µm
