Depth of Field for the Ricoh GR III
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 Ricoh GR III using the exact dimensions of its 23.5×15.6 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 Ricoh GR III?
0.019 mm — the standard sensor diagonal ÷ 1500 convention, applied to the Ricoh GR III's exact sensor.
What is the hyperfocal distance for a 50 mm lens on the Ricoh GR III?
About 16.7 m at f/8 — focus there and everything from 8.33 m to infinity is acceptably sharp.
Does the Ricoh GR III have a crop factor?
1.53× — a 50 mm lens frames like a 77 mm lens on full frame. See the crop factor guide.
