Photographer Joe has been using his 85mm \"portrait\" lens on his 1.6x crop factor camera. He likes the results, but he hears that FF cameras will give him less DOF, allowing him to isolate his subject more.
So, photographer Joe rents or buys a shiny FF camera. He wants to see how his portraits are going to look, so he goes out to the park with his kid and his 85mm \"portrait\" lens on his new camera.
He gets home and cannot believe his eyes. \"Wow! look how shallow the DOF is!\" His conclusion is that the DOF is shallower on his new camera.
We all know what really happened (don\'t we?).
He framed his subjects as he always did. His style has not changed, after all. In order to maintain the same shots that he did before, he moved closer.
Now, IMO, it doesn\'t really matter whether this DOF difference is due to the camera or due to the photographer. In fact, I think it doesn\'t even really matter if photographer Joe is aware that he is the cause of the reduced DOF.
