Another success story!
Dave our lead repair technician was able to repair the manual focusing system and clean the optics on a lens that Nikon factory refused to work on. This Nikon 400mm f/2.8 AF-S is an expensive lens, one certainly worth repairing! To replace it with a newer version (the VR II) is around $6000. That being said, it’s hard for me to think the manufacturer would choose not to work on it, because it’s too old.
