Exactly my point.

Again, exactly my point. At any given focal length, the lens projects a narrower field of view on an DX body and the flash can zoom in.

The OP said that a 50mm DX lens on a DX body has the same FOV as a 50mm FX lens on an FX body. That isn't so. That was my point.

A 50mm DX lens might be smaller, lighter, and less expensive, because it does not have to have the same image area. It does not produce the same FOV on a DX sensor as a 50mm FX lens does on an FX sensor though.
