In the old days of 35mm film cameras it was easy to find depth of field tables which are critical for determining the distances that will be acceptably in focus at various lens apertures and focal lengths. It even used to be indicated on lenses.
It got harder with digital cameras since the sensors are different sizes and sensor size makes a huge difference to depth of field.
I've been looking for a handy table for a while and even wrote my own spreadsheet to calculate them for my camera.
Then I finally found a good on-line one that lets you select your specific camera, plug in the lens focal length (actual NOT 35mm equivalent) and if you don't happen to know it has look up tables for a whole range of digital cameras - from compact to SLR's.
You can find it, along with some good explanations of how depth of field works at:
