With the F/Calc, I computed, using a circle of confusion for APS film size (because the COC formulation is for 20x30cm prints, and I do bigger than that, so I need smaller COC), that I get DOF from 1m to infinity if I focus my 20mm at 2m and set f/8. I generally shoot this in good light forgetting about focus altogether (which is good as the lens is M42 used via adapter, and at f/8 I can't focus anyway due to dark view). But if I shoot something critical, and have time, I focus even with such DOF, as it will show. Good light, Frantisek Vlcek - This message is from the Pentax-Discuss Mail List.
