When to use it#
At f/4, a 14 mm lens on full frame is a natural choice for general photography. Focused at 3 m you get everything to infinity; for maximum front-to-back sharpness focus at 1.65 m and everything from 82.4 cm to infinity will be acceptably sharp.
See also the f/4 aperture guide.
Frequently asked questions#
What is the depth of field of a 14mm lens at f/4?
On full frame, focused at 3 m, it is infinite (beyond the hyperfocal distance); at 1 m it is 1.90 m.
What is the hyperfocal distance for 14mm f/4?
1.65 m (5.40 ft) on full frame. Everything from 82.4 cm to infinity is acceptably sharp.
