[QUOTE="JDFlood, post: 169122, member: 11653"] The answer is complicated. It has been addresses several times before, I would search. There are several good sites which discuss it. I would get one of the iPad apps that addresses DOF, and you can watch what happens. Let me see if I can say this right. For the same distance with the same focus length lens the FX DOF is actually bigger ( but the DX camera has a larger FOV), however for the same distance from the subject with the same focus length lens the DOF is larger for the DX but the image is more magnified with the FX. What fStop you use should be determined by the subject. This is where a DOF app is useful. Also, it does change with the focus length of the lens. There are sites that explain this pretty well. It is hard to explain clearly in a few words. JD [/QUOTE]
