A post from Nikonrumors said that Nikon will soon mark their 70 million Nikkor lenses milestone. It took Nikon 6 months to produce 5 Million lenses in 2011, 65 Million lenses were announced in October 2011, the 60 million milestone was in April, 2011.
The official press release will probably come out with the new Nikkor 24-85mm f/3.5-4.5 VR full frame lens, maybe this Friday.
