When to use it#
At f/11, a 20 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 1.23 m and everything from 61.6 cm to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 20mm lens at f/11?
On full frame, focused at 3 m, it is infinite (beyond the hyperfocal distance); at 1 m it is 4.67 m.
What is the hyperfocal distance for 20mm f/11?
1.23 m (4.04 ft) on full frame. Everything from 61.6 cm to infinity is acceptably sharp.
