When to use it#
At f/8, a 50 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 1.85 m of sharp zone; for maximum front-to-back sharpness focus at 10.5 m and everything from 5.23 m to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 50mm lens at f/8?
On full frame, focused at 3 m, it is 1.85 m; at 1 m it is 18.4 cm.
What is the hyperfocal distance for 50mm f/8?
10.5 m (34.3 ft) on full frame. Everything from 5.23 m to infinity is acceptably sharp.
