Depth of field table
Distances are measured from the sensor plane. Each cell shows the near and far limit of acceptable sharpness in metres (∞ = to infinity). Circle of confusion = sensor diagonal / 1500.

FAQ
What is the depth of field of the Olympus M.Zuiko 12-40mm F2.8 PRO II at f/2.8 and 3 m?
At 24mm, f/2.8 and focus at 3 m, acceptable sharpness runs from 2.48 to 3.79 m — about 131 cm in total.
What is the hyperfocal distance of the Olympus M.Zuiko 12-40mm F2.8 PRO II?
At 24mm and f/8 on a Micro Four Thirds sensor the hyperfocal distance is about 5.01 m. Focus there and everything from 2.51 m to infinity is sharp.
How do I get more background blur with the Olympus M.Zuiko 12-40mm F2.8 PRO II?
Open the aperture to f/2.8, move closer to your subject and increase the distance between subject and background, and zoom in to the long end. You can check the result in the calculator above.
