Yes, indeed you did. I was merely adding my personal observation that, at the time that Vivitar was celebrating its anniversary, high quality in VS1 lenses had become a thing of the past (in my humble opinion). > They are however a match for the finish, after all who in their right > mind would actually use them to take pictures. Well, these particular eBay lenses ~may~ actually have been used - they were certainly not in mint "collector's condition" - they were merely "excellent", perhaps in "9" condition. As for actually using these models, I'm willing to use the (5th-generation) Q-DOS 3-D version of that 4th-generation 70-210, just because it's fun to use, even though its optical and build qualities are less than that of the sweet first three VS1 70-210's.
