This page contains charts of the minimum required camera-to-target distances that provide enough depth of field so that there is acceptable defocus blur with the target at the corners of the image when a 24 megapixel APS-C camera is focused with the target centered. In the case of these charts, the acceptable circle of confusion (CoC) is defined to be one-half the camera’s pixel pitch.
There are three charts, with the lens focal lengths getting larger as one proceeds further down the page.
