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 24mm F1.8 Macro IS STM at f/1.8 and 3 m?

At 24mm, f/1.8 and focus at 3 m, acceptable sharpness runs from 2.37 to 4.10 m — about 173 cm in total.

What is the hyperfocal distance of the Canon RF 24mm F1.8 Macro IS STM?

At 24mm and f/8 on a Full Frame sensor the hyperfocal distance is about 2.52 m. Focus there and everything from 1.26 m to infinity is sharp.

How do I get more background blur with the Canon RF 24mm F1.8 Macro IS STM?

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.
