Depth of field by subject distance#
50 mm at f/11 on full frame (36×24 mm), circle of confusion 30 µm. “Background blur” is the size of an out-of-focus light at infinity as a percentage of frame width.

When to use it#
At f/11, 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 2.75 m of sharp zone; for maximum front-to-back sharpness focus at 7.63 m and everything from 3.81 m to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 50mm lens at f/11?
On full frame, focused at 3 m, it is 2.75 m; at 1 m it is 25.5 cm.
What is the hyperfocal distance for 50mm f/11?
7.63 m (25.0 ft) on full frame. Everything from 3.81 m to infinity is acceptably sharp.
