Re: Olympus 30 vs 60 Macro Lens - Which one's a keeper?

I’m not sure what you meant by “calculations”. I obtained the DOF figures directly from the DOF tables that are provided in the references I gave. I ignored the figure for the 30mm lens at f/22, because diffraction blurring would negate any advantage of the slightly wider DOF (2mm) at f/22 and 10cm. So for practical purposes, the DOF is very little for the 30mm lens at a field size of 17x13mm.
