Hello, everybody! It was snowing yesterday despite the sakura trees being in full-bloom. This is a rare occurrence, something that not a lot of people experience in their lifetimes. It’s like watching Tom Jones perform with his stable-mate Engelbert Humperdinck at a pub, can you imagine that? This is my first time to experience such a thing and this will certainly stay with me for a very long time. Speaking of rare occurrences, I’ll show you a rare lens that many people don’t see often. It was only made for over-a-year and that is the reason why it’s rare. Owning one is special but I have two of these so that makes it even better.
Introduction:
The Nikkor-S 5cm f/2 Auto was made from 1959 to 1963, it is the first 50mm lens for Nikon’s then-new F-mount. The flapping mirror of an SLR became a challenge for lens designers back because existing rangefinder lenses have long rears that will hit the mirror. This became such a problem that making a “standard” 50mm lens became a challenge. Nikon had to improvise just to create a proper 50mm lens for the Nikon F and the solution was to have the front element act as a sort of “magnifying element” to achieve a 50mm AOV or angle-of-view. It’s a stop-gap until the Nikkor-H 50mm f/2 Auto succeeded this lens a few years later.

Admire the beautiful lines in the aperture and focusing rings, these are the reason why the earliest F-mount Nikkors are called “tick-mark” lenses by the majority of the Nikon collectors community. It’s a throwback to rangefinder Nikkors, to an era where craftsmanship reigned supreme.
