It's not about field of view (a f/2.0 wide angle and telephoto shot both have the same DOF in terms of actual length - telephoto just appears to have a shallower DOF since the image is cropped.) DOF is actually a physical property of sensor size and aperture size. http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htm http://www.cambridgeincolour.com/tutorials/digital-camera-se...
