Depth of field by subject distance#
600 mm at f/5.6 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/5.6, a 600 mm lens on full frame is a natural choice for general photography. Focused at 3 m you get 0.7 cm of sharp zone; for maximum front-to-back sharpness focus at 2.1 km and everything from 1.1 km to infinity will be acceptably sharp.
