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 15mm F1.4 G at f/1.4 and 3 m?
At 15mm, f/1.4 and focus at 3 m, acceptable sharpness runs from 2.22 to 4.61 m — about 238 cm in total.
What is the hyperfocal distance of the Sony E 15mm F1.4 G?
At 15mm and f/8 on a APS-C sensor the hyperfocal distance is about 1.51 m. Focus there and everything from 0.76 m to infinity is sharp.
How do I get more background blur with the Sony E 15mm F1.4 G?
Open the aperture to f/1.4, move closer to your subject and increase the distance between subject and background. You can check the result in the calculator above.
