[QUOTE="crycocyon, post: 122950, member: 13076"] Sorry, I meant to say subject distance in terms of providing the same FOV, then DOF will be greater with the DX. However, if distance to subject, f stop, focal length, and the final images are the same size, the DX will have less DOF. Also, if you change sensor size, you would need a different angle of light to fill the sensor, and therefore a different focal length. DOF ratio is in direct proportion to format size when using the same focal length, same subject distance, and the same f-stop, and inversely proportional to format size when focal length is adjusted at same subject distances to give the same size final image. So DOF is intimately associated with format size, because it is derived from not only what the light is being projected FROM, but also where the light is being projected TO. [/QUOTE]
