The physical size of the DX sensor is not as large as a 35mm frame just like a 35mm frame is not as large as medium format frame. So to say that the DX is not full frame would be like saying 35mm is not full frame because a medium format frame is larger.
To say one sensor size is full frame while another isn't is nonsense.
Its FF or not in relation to a normal 35mm frame, you remember FILM dont you ?
If youv've been a film shooter before, all your lenses are going to give you a certain FOV. a 50mm is going to give you a certain head and shoulders framing from a certain distance you are used to. If you switch to a 1.5x crop sensor, from that same distance your not getting the same framing.
Thusly, in terms of the way 35mm lens are designed, cropped sensors are not full frame because they dont cover the area of 35mm film. A normal lens is projecting an image circle that is larger than the sensor area, unless your using the new DX and similar aps-c lens which are designed for smaller sensors
If you put a DX lens on a 35mm film camera, you'd only get an image in the center of your frame.
Thusly, the difference between FF and cropped sensors
