Depth of Field Calculator for the OM System OM-1 II
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 OM System OM-1 II using the exact dimensions of its 17×13 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 OM System OM-1 II?
0.014 mm — the standard sensor diagonal ÷ 1500 convention, applied to the OM System OM-1 II's exact sensor.
What is the hyperfocal distance for a 50 mm lens on the OM System OM-1 II?
About 21.6 m at f/8 — focus there and everything from 10.8 m to infinity is acceptably sharp.
Does the OM System OM-1 II have a crop factor?
1.99× — a 50 mm lens frames like a 100 mm lens on full frame. See the crop factor guide.
