The question assumes 100% fill factor and round :-O pixels, to keep the question simple. Let's say that, for a particular set-up, a CoC calculation (rightly or wrongly) gives a value of 0.014mm at the sensor but I insist on using 2x2 binning on a Sigma SD9 or SD10 giving an 0.018mm 'diameter' pixel. Would the DOF be that for 0.014mm or that for 0.018mm? Putting that another way, does the sensor pixel density px/mm^2 have an intrinsic DOF when projected out to the subject plane? I'm thinking...
