Take it and use it how you will. I hearby release it under a Creative Commons "Do whatever the hell you want with it, man. I don't care" license. (Forgive me. I don't know the actual license name.)
It's based on Canon's DOF chart (which I've found in meters only) found here, and this online meters-to-feet conversion utility. All I really did was save you some cutting and pasting. Consider it my gift to you, semi-anonymous future internet visitor.
