Depth of Field Calculator for the Leica Q3
Depth of field is the range of distances in a scene that appears acceptably sharp in front of and behind the focus point. This page computes it for the Leica Q3 using the exact dimensions of its 36×24 mm sensor — no generic presets.

How to use this page
Find your lens and aperture, read the near–far range, and either compose within it or click the button to open the interactive calculator and drag the focus distance live. Landscape shooters should look at the hyperfocal column: set the lens to that distance and everything from half of it to infinity is sharp. For a full explanation of the formula and the circle-of-confusion convention, see the circle of confusion guide.

Frequently asked questions
What is the circle of confusion for the Leica Q3?
0.029 mm — the standard sensor diagonal ÷ 1500 convention, applied to the Leica Q3's exact sensor.
What is the hyperfocal distance for a 50 mm lens on the Leica Q3?
About 10.9 m at f/8 — focus there and everything from 5.44 m to infinity is acceptably sharp.
Does the Leica Q3 have a crop factor?
1.00× — a 50 mm lens frames like a 50 mm lens on full frame. See the crop factor guide.
