Depth of Field Calculator for 7D , 5D, a100, a200, a300, a350 and a700

How to use the light choices:
Green: It is the value to use most images.
For precision work (e.g. where you measure the distance to the subject) use Red or Blue.
Red: To guarantee that a subject INSIDE the DOF will be IN FOCUS throughout the entire visible spectrum.
Blue: To guarantee that a subject OUTSIDE the DOF will be OUT OF FOCUS throughout the entire visible spectrum.
When using Red or Blue you will likely need to measure the distance from the subject to the CCD-plane indicator on the camera body

*Use focal lenght as indicated on your lens
