24mm f/1.4 depth of field
On a full-frame camera, a 24 mm lens at f/1.4 focused at 3 m (9.84 ft) is sharp from 2.47 m to 3.83 m (1.37 m deep). Hyperfocal distance: 13.7 m (45.1 ft).
Advanced
Leave empty to use the standard value for the sensor. Halve it for pixel-level sharpness.
With a 24 mm lens at f/1.4 on full frame focused at 3.00 m, everything from 2.47 m to 3.83 m is acceptably sharp: 1.37 m of depth of field.

Astro and environmental portraits
Twenty-four millimetres wide open is a favorite for night skies and for people in their surroundings. At f/1.4 the depth of field is surprisingly thin for a wide lens: a person at 2 m is sharp, but the background softens noticeably.
For stars, focus at infinity (manual focus on a bright star with magnified live view); the hyperfocal distance at f/1.4 is almost 14 m.

The same lens on other sensors (focused at 3 m)
Same lens, same distance — smaller sensors frame tighter and use a smaller circle of confusion.

FAQ
How much depth of field does a 24mm f/1.4 lens have?
On full frame, focused at 3 m, the sharp zone runs from 2.47 m to 3.83 m (1.37 m deep). At 1 m it is 14 cm. Depth of field grows roughly with the square of the distance.
What is the hyperfocal distance of a 24mm lens at f/1.4?
13.7 m (45.1 ft) on full frame (c = 0.030 mm) and 20.6 m (67.6 ft) on APS-C. Focus there and everything from half that distance to infinity is acceptably sharp.
Is depth of field different with 24mm f/1.4 on an APS-C camera?
With the same lens at the same distance, APS-C gives slightly less depth of field (89 cm at 3 m) because of its smaller circle of confusion — but it frames like a 37 mm lens. To match the full-frame framing you would step back, which increases depth of field.
