....I think we are saying the same thing here - not sure if you are just adding some more detail to my comment, or if my message was mis-understood.

Basically, all other things being equal:-

  • f2.8 gives a shallower Dof vs f4

  • FF gives shallower DoF vs Cropped sensor

So the advantage of shallower DoF of the FF is somewhat cancelled out by the not so shallow Dof of the f4 lens....and....

.....the shallower Dof of the f2.8 lens is somewhat cancelled out by the not so shallow DoF effects of a crop sensor.

......with the ideal (shallowest DoF) being the f2.8 on a FF sensor.

Hope that clears things up abit.
