The Nikon 28-70mm f2.8d lens is still an optical wonder for the time it was manufactured. Mine is in excellent condition, looks hardly used. I am still amazed how it stands up against the newer Nikon zooms. Mine has not squeak and focuses extremely fast. It is a huge lens but the optical quality overrides the size. It is my event and a lot of other uses. Old is not allows that much worse and better than a lot of lenses than new, especially for this lens.
