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 Sigma 100-400mm F5-6.3 DG DN OS at f/5.4 and 3 m?
At 200mm, f/5.4 and focus at 3 m, acceptable sharpness runs from 2.97 to 3.03 m — about 7 cm in total.
What is the hyperfocal distance of the Sigma 100-400mm F5-6.3 DG DN OS?
At 200mm and f/8 on a Full Frame sensor the hyperfocal distance is about 174 m. Focus there and everything from 86.8 m to infinity is sharp.
How do I get more background blur with the Sigma 100-400mm F5-6.3 DG DN OS?
Open the aperture to f/5.4, 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.
