However this was introduced mid 90s I think so some professional glass out there still in common rotation and still being sold (85mm f/1.4 or the 80-200 f/2.8 AF) have no gold ring. Certainly all the new ones do. Don't confuse not stooping to such marketing ploys with just being late to brand products which have a very very long life cycle."
Sorry Garbz, but you're wrong about the gold ring. First off, it was not introduced in the "mid-1990's". Nikon introduced the gold ring on ED telephotos in 1975 with the 300 f/4.5 ED 600mm f/5.6ED, Nikkor 880mm f/8.0 ED, and 1200mm f/ 11 ED.
You're about twenty years too late my boy....the Nikkor 400mm f/3.5 ED-IF was premiered at the 1976 Montreal Olympics, with ED glass and...a gold ring. The 400mm f/3.5 was the world's fastest supertelephoto lens for some time, until Nikon introduced an f/2.8 version.The 400mm f/5.6 Nikkor also had a gold ring,even though it was not the professional-level model 400mm, but it had ED glass.
The AF-D Zoom Micro-NIKKOR 70-180mm f/4.5~5.6 did not have a gold ring. One of the all-time best-ever professional-grade macro lenses was the 200mm f/4 ED-IF Micro-Nikkor--again, ED glass, but no gold ring The relatively pedestrian 70-300mm AF-D Nikkor has ED glass, but no gold ring. Nikon's current 180mm AF-D is an f/2.8 ED f/2.8 ED glass telephoto,and it has no gold ring. Nikon's 80-200 f/2.8 ED zooms in autofocus variants 1 and 2 and 3 had ED glass, but no gold rings,and ran from 1988 to 1998, and the 80-200 f/2.8 ED AF-S model had ED glass, but no gold ring during its run from 1996 to 2006.
Again, you're wrong about the gold ring as a signal or identifier for Nikon's "pro glass". Many of their professional-grade lenses,even current models, have no gold ring on them. Again, Nikon has long counted on its user base to understand what makes a professional lens--and it's far from being a simple marketing gimmick like putting a stripe around lens barrels. From 1988 to 2006, Nikon's 80-200mm f/2.8 zooms had NO gold ring, but were pro lenses. Same with their professional macro lenses.
Serious Nikon users know what professional lenses are; they do not need to be "told" what to consider a professional-grade lens...and this has been true for well over 20 years now.
