When to use it#
At f/11, a 28 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 2.40 m and everything from 1.20 m to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 28mm lens at f/11?
On full frame, focused at 3 m, it is infinite (beyond the hyperfocal distance); at 1 m it is 98.3 cm.
What is the hyperfocal distance for 28mm f/11?
2.40 m (7.89 ft) on full frame. Everything from 1.20 m to infinity is acceptably sharp.
