Depth of field by subject distance#
85 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 85 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 81.3 cm of sharp zone; for maximum front-to-back sharpness focus at 22.0 m and everything from 11.0 m to infinity will be acceptably sharp.
