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 Sony E 11mm F1.8 at f/1.8 and 3 m?
At 11mm, f/1.8 and focus at 3 m, acceptable sharpness runs from 1.64 to 18.0 m — about 1639 cm in total.
What is the hyperfocal distance of the Sony E 11mm F1.8?
At 11mm and f/8 on a APS-C sensor the hyperfocal distance is about 0.82 m. Focus there and everything from 0.41 m to infinity is sharp.
How do I get more background blur with the Sony E 11mm F1.8?
Open the aperture to f/1.8, move closer to your subject and increase the distance between subject and background. You can check the result in the calculator above.
