Randy,

Physical size of the sensor is only partially responsible for the depth of
field, but in the opposite way that would help in this case.  Smaller
formats require smaller CoCs (Circle of Confusion), which means less DOF.
The lense is the other part of the equation, and the lense required to be
used to get the image sized correctly with a smaller sensor would be a wider
angle lense, which has higher DOF.  I have to think about that.

Regards,

Austin
