Nikon today announced that they've produced 50 million Nikkor lenses. 50 weeks ago, they announced they had produced 45 million Nikkor lenses. I say the announcement is curious because the number produced seems slightly higher than the number shipped (by 4% to be specific). I write "seems" because there is a bit of disparity in the dates that make such bookkeeping a bit difficult to track, but there has been nothing to indicate that Nikon has bumped up shipments in the past couple of weeks. I suspect we've got another lens announcement coming soon.
For those trying to keep track, here are the dates of significant milestones for Canon (EF mount), and Nikon (F mount):

| 7/2007 | 40m | |
