Very nice.
Note that the thing about the calculator automatically adjusting for any "field of view crop" is a bit of a red herring.
The depth of field equations do not care in the slightest about format size - assuming that we feed in our chosen value of the
circle of confusion diameter limit (COCDL).
But if we want the calculator to choose a COCDL for us that is "appropriate" for our camera's format size (based on the common rule of thumb of a certain fraction of the diagonal size of the format, often 1/1400 or thereabouts), then of course format size gets taken into account that way. (This is what that calculator does when we select a camera family rather than a COCDL).
