The foundation of all Nikon d80 lenses is the Nikkor Lens Technology. Nikon has been the leader in lens technology for many decades now and has become a standard baseline and has set the benchmark for many other digital SLR camera companies. One of the most amazing things with every single Nikon d80 lens is that whenever they upgrade a lens, it will retail all existing features so you will never lose anything you love about a particular Nikon d80 lens, you will only gain new features.
