My brain has turned to a pretzel.

How do you account for the FX/DX factor when using a DOF calculator.

There are a bunch of them available (mostly free) for iPhones and Android, but it struck me that I'm not sure whether to calculate for a 35mm or 52mm lens when using a DX camera. I've been assuming that you use the actual lens diameter, but that really gives a huge DOF advantage to DX, doesn't it?

Your addled pals,
