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 Canon RF 85mm F2 Macro IS STM at f/2 and 3 m?

At 85mm, f/2 and focus at 3 m, acceptable sharpness runs from 2.93 to 3.07 m — about 14 cm in total.

What is the hyperfocal distance of the Canon RF 85mm F2 Macro IS STM?

At 85mm and f/8 on a Full Frame sensor the hyperfocal distance is about 31.4 m. Focus there and everything from 15.7 m to infinity is sharp.

How do I get more background blur with the Canon RF 85mm F2 Macro IS STM?

Open the aperture to f/2, move closer to your subject and increase the distance between subject and background. You can check the result in the calculator above.
