Visualization of DOF

Here you can see how you can achieve the same DOF on different sensor sizes by choosing appropriate lenses .

DOF equations taken from wikipedia. I have used http://www.dofmaster.com/equations.html initially but they produce almost the same result. I'm using wikipedia because you can see how equations are derived and what it means.

While sliders have limits you can type anything to text fields.
