Depth of field by subject distance#
600 mm at f/8 on Micro Four Thirds (17.3×13 mm), circle of confusion 15 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/8, a 600 mm lens on Micro Four Thirds is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get 0.5 cm of sharp zone; for maximum front-to-back sharpness focus at 3.0 km and everything from 1.5 km to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 600mm lens at f/8?
On Micro Four Thirds, focused at 3 m, it is 0.5 cm; at 1 m it is not applicable (inside minimum focus).
What is the hyperfocal distance for 600mm f/8?
3.0 km (9844 ft) on Micro Four Thirds. Everything from 1.5 km to infinity is acceptably sharp.
