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 105mm F1.4 DG HSM Art at f/1.4 and 3 m?

At 105mm, f/1.4 and focus at 3 m, acceptable sharpness runs from 2.97 to 3.03 m — about 6 cm in total.

What is the hyperfocal distance of the Sigma 105mm F1.4 DG HSM Art?

At 105mm and f/8 on a Full Frame sensor the hyperfocal distance is about 47.9 m. Focus there and everything from 23.9 m to infinity is sharp.

How do I get more background blur with the Sigma 105mm F1.4 DG HSM Art?

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.
