Depth of field by subject distance#
16 mm at f/2 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/2, a 16 mm lens on full frame is a natural choice for environmental portraits, street and low light. Focused at 3 m you get 8.21 m of sharp zone; for maximum front-to-back sharpness focus at 4.28 m and everything from 2.14 m to infinity will be acceptably sharp.
