What does

[TMoriarty]

Some Nikon lenses have the word Nikkor in their names while others do not. For example, the following two 50mm's:
"Nikon 50 mm f/1.8D Nikkor AF Lens" and "Nikon 50 mm f/1.4D AF Lens ".

Obviously one lens is faster than the other, but what about the Nikkor moniker?

On the Nikon USA web site they're listed as:

• 50mm f/1.4D AF Nikkor
• 50mm f/1.8D AF Nikkor

The designation Nikkor used by Nikon to identify its line of lenses, just like Pentax Takumar, Olympus Zuiko, Minolta Rokkor...

There was a split with the Nikon "Series E" lenses were introduced, more "economy" versions of many of the Nikkors they overlapped. I believe the Series E lenses were the only manual focus for 35mm SLR Nikon lenses not to carry the Nikkor name.

But now, basically all Nikon lenses are "Nikkors":
