Depth of field by subject distance#
24 mm at f/11 on full frame (36×24 mm), circle of confusion 30 µm. “Background blur” is the size of an out-of-focus light at infinity as a percentage of frame width.

When to use it#
At f/11, a 24 mm lens on full frame 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 1.77 m and everything from 88.5 cm to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 24mm lens at f/11?
On full frame, focused at 3 m, it is infinite (beyond the hyperfocal distance); at 1 m it is 1.63 m.
What is the hyperfocal distance for 24mm f/11?
1.77 m (5.81 ft) on full frame. Everything from 88.5 cm to infinity is acceptably sharp.
