Depth of field by subject distance#
85 mm at f/16 on APS-C (23.5×15.6 mm), circle of confusion 20 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/16, a 85 mm lens on APS-C is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get 78.8 cm of sharp zone; for maximum front-to-back sharpness focus at 22.7 m and everything from 11.3 m to infinity will be acceptably sharp.
