It's not as if I don't understand your frustration. I do. In fact rest assured that it hit me a couple of times.

 

However, this is still not comparable to the recent bubbles-on-sensor issue over at Canon, the brutal (and still unresolved) shutter-shock at Sony or even your average centering problem where something as simple as a firmware update isn't possible.

 

You may ask Nikon, however, why user-updates are still not possible for Nikkor lenses. It's not exactly science fiction.
