ok, I hate to keep hitting this dead horse with a stick but I would love to see some examples of DOF on 2.8 versus 4.0 Using the Canon 70-200L lenses.

because when I look at this site
http://www.dofmaster.com/dofjs.html

A subject 15 feet away and having the lense set at 100MM at 2.8 gives me a DOF of .72 feet versus at 4.0 gives me a DOF of 1.02 feet

I know the bokah will be slightly different but will it be enough to justify shooting at 2.8

any examples would be great
