While most of us applaud Nikon for maintaining the same lens mount for all these years, this is one area where we have to give something up because of it. The rear element of the shorter lenses sits so close to the mount that the inside diameter of the mount limits the maximum aperture possible. I don't it's possible to achieve f1.0 with a 50mm lens given the current Nikon mount. -Don
