Trying to explain the confusion about focal length when manufacturers put in the confusing term of Equivalent into the sales speech. Focal length on all dslr lenses are measured in MM (millimeters) and if it is a 50mm lens on a full frame camera it is still a 50mm lens on a cropped frame camera but the only difference is you see less of the bits at the side making it look like it is zoomed in, but the perspective is not changed so it is the same as putting a toilet roll around your eye, your eye still has the same perspective you just cant see stuff round the edges

Have to disagree with your comment about DOF on a crop sensor camera and a FF camera. You said you don't get greater DOF. But you are not taking the same picture. If you take the same picture with a crop sensor and a FF, you must use the same field of view. That means you must step closer to the subject with a FF camera, but DOF and perspective change when you do that but it is the only way to take the same picture. If the distance to subject does not change, I agree, but then the image is cropped and it is no longer the same picture.
