How shallow do you want?

At 10 m distance, assuming 0.03 mm Circle of Confusion, DOFmaster tells us that depth of field extends from 9.95 m to 10.05 m for the 800 mm lens at f/11.

Oh my, it is so rare to see someone actually specify the circle of confusion in their DoF calculations.

Alan, I love you even more than I already did.
