I'm not sure that you would get greater DOF. DOF is pretty much defined
by the diameter of the aperture, the distance to the target, and
reproduction size. I think I'd actually have to work out the math of a
100mm f2.8 vs an 560mm (assume f5.6) for a particular distance and
reproduction size to know for sure. I don't think I want to do that,
because I'm basically lazy.

have the AOV of a 560mm lens on 35mm using that lens with the Q.
Which is super telephoto by any definition. You could also get the
same effect by using that lens on a ff sensor with 72mp and cropping
to 12mp from the center of the frame. (I know of no manufacture
making a 72mp ff sensor so don't ask, I just multiplied in my head
which is less sure than it used to be so if I'm wrong tough).
