When to use it#
At f/2.8, a 14 mm lens on full frame is a natural choice for environmental portraits, street and low light. Focused at 3 m you get everything to infinity; for maximum front-to-back sharpness focus at 2.35 m and everything from 1.17 m to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 14mm lens at f/2.8?
On full frame, focused at 3 m, it is infinite (beyond the hyperfocal distance); at 1 m it is 1.03 m.
What is the hyperfocal distance for 14mm f/2.8?
2.35 m (7.70 ft) on full frame. Everything from 1.17 m to infinity is acceptably sharp.
