An interesting little advert. No doubt intended to get the average Leica Fanboys heart racing! lol
An assortment of F-series Nikons (F to F6, excluding the F4) with quite a few Nikkors, a pair of M6s with some Leitz glass, a pair of 500c/ms with a wide range of Zeiss optics and, just to help keep Duracell solvent, a D800.
I thought the amount of dust on the lens element at 1:44 is amazing... and that she is handling lens elements with her bare hands. Hopefully she just had the gloves off for the video.
Typical advertising fluff, superficial to the point of being misleading. It would take a long series of one-hour programs to do any justice at all to the science of lens design and the near-art of manufacture. "Manual blackening of lens edges, for a perfect result" or some such...
When after WWII the Japanese started making cameras and lenses which were every bit as good as Leitz, Leitz realised that, even though they made exceptionally good cameras fitted with exceptionallly good lenses they couldn't compete with Japan without some kind of gimmick. In the 1950s, you could find ads for Leica in fashion magazines, travel mags, etc. This was the beginning of Leica KoolAid. Pros bought Leicas for the quality, the rest for the image. It was the image buyers that kept Leica in business, much like Rolex.
But I still found it interesting just to see some of the steps being performed. For example, we all know that engraving is an automated process. But I had never actually watched the tooling perform that task on a lens. Kinda' neat to see.
I'm not so much worried about secondary or tertiary ulterior motives. Just the experience of seeing and learning new things is always rewarding to me all by itself.
