Default Canon EF 100mm f/2.8 Macro L IS: Depth of field chart wanted

Thanks for all help. I got an iPad app that calculates depth of field
for combinations of variables.


You know that DoF is just one part of the sharpness story? Most people
realise pretty soon that it fails to deliver on the promise. To get the full
picture, you'd also have to take into account diffraction and object field
resolution.
