What makes this lens cool? Adam, what makes it so cool?

It’s beautifully made, a gorgeous combination of metals, glass and enamel paint. Engineered by talented designers during a time of innovation, a lens that was built in a different time.

And it’s mine. I got it for a song. I have one of its sister lens, the AI Zoom Nikkor 35-200 f3.5-4.5S. I’m excited to complete the trio by collecting the AI Zoom Nikkor 35-135 f3.5-4.5S

I’ll use them on the FE.

I love AI-S lenses. I’ve owned more than two dozen and I’ve sold every last one of them to buy second and third generation F-mount auto focus D and G series lenses. I ended up regretting that decision. Ultimately, I have repurchased a couple already. This one, I never had or held or even knew it had a connection to one of my favorite lens.

Give me a moment, I’m going to research a little bit about it, another reason why I am intrigued. They are well documented.

Google AI brought me to Nikkor - The 1001 Nights No 71. The lens in the story is the AI Zoom Nikkor 35-105 f3.5-4.5S Why the S at the end? This lens came out in 1983, a transitional time at Nikon. The AI Zoom Nikkor 35-105mm f3.5-4.5S was a transitional lens from previously bulky manual focus lenses to the compact walk around lens designed for the FM and about the time of the release of the F3. I owned an F3 and loved it but sold it. It didn’t represent what I wanted out of a purely manual focus experience. It was a digital viewfinder info display and I wanted a double needle. I really enjoy researching the history and having, owning and operating this classic equipment is a fantastic experience.

I’m not a plagiarist, you should read the story at Nikon, a story about a time that was filled with change, reorganization and the designer, Tomowaki Takahashi, an optical engineer at Nikon. Takahashi San wrote a book, “Lens Design: From Aberration Coefficient to Automated Design” I looked for it but could not find it, I did find a PDF at Nikon that references it HERE.

Anyway, I will look more thoroughly for the book later.

Researching manual focus zoom lenses, I learn the story of the Nikon system AND I already own one of the two lens that Mr. Takahash designed. The AI Zoom Nikkor 35-200 f3.5-4.5S. It’s sort of interesting how I picked out that lens out of all the choices available. I now own both and I’m excited to start using the AI Zoom Nikkor 35-105 f3.5-4.5S.

There are so many good resources that have reported on Nikon manual focus lenses. I’m going to focus on three. The MIR site on the Zoom-Nikkor 35-105mm f/3.5~4.5s MACRO, the 1001 Nights Nikon series and Richard Haws site on the repair of this lens. Take a look if you are interested.
