A camera is only as good as it's lens, just as a lens only as good as the camera.
And both are only as good as the accuracy with which they are mate. In the Nikon system,
camera and lens are engineered to function as a unit. The underlying concept transcends
optical and mechanical factors to archievethis perfect unity of interchangable components.
Nikon call it TSR (Total System Resolution) Every Nikkor lens is designed
to fulfil its own vital role in the TSR concept
