Depth of Field Calculator for the Sony A1 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 Sony A1 II 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.
