When to use it#
At f/16, a 24 mm lens on APS-C is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get everything to infinity; for maximum front-to-back sharpness focus at 1.82 m and everything from 91.2 cm to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 24mm lens at f/16?
On APS-C, focused at 3 m, it is infinite (beyond the hyperfocal distance); at 1 m it is 1.54 m.
What is the hyperfocal distance for 24mm f/16?
1.82 m (5.98 ft) on APS-C. Everything from 91.2 cm to infinity is acceptably sharp.
