Dof

Am I correct in thinking I'll get better DOF in macro shooting with my D300 than with my D700 due to the smaller sensor size?

I believe so but not sure because i only own a crop sensor camera. You could just try it out of course

i dont believe
DOF is all about aperture
and thus about light

In general, crop sensors have greater DOF. See

I just read a piece by the landscape photographer Carl Heilmann who said that this is the reason that he still uses a crop sensor camera for some of his work.

However, DOF behaves oddly at macro distances, so maybe not as much of a difference in this case. I have only shot macro with a crop-sensor camera, so I have no experience. A few people on this forum have shot both.

I believe the following statements are true for a FF camera vs a crop frame camera. When viewing a print of the same size

.1 With the same lens and same subject distance and aperture a FF camera will give more DOF.
.2 With the above constraints but using a longer focal length lens on the FF camera to give the same FOV as the crop camera, the crop camera will give more DOF.

.3 With macro the limit on DOF via aperture tends to be linked with diffraction softening of image. It happens that the same diffraction level is actually achieved at exactly the same DOF level for either camera type. In other words at the same print magnification you can shoot the FF camera around 1 stop smaller aperture (ie higher f number) to give the same level of diffraction as the crop camera which equalises any DOF differences.
