He probably read Rockwell to learn about an SP.
Here is the list from Nikon:
Nikon Imaging | Legendary Nikons
I do not have a Nikon I, the S3M, an F4, or a Titanium Nikon.
The others on that list, I have. Plus a lot that did not make it onto the list. Anyone else have a Nikon E3? It's Nikon DSLR from 1997, full-frame acheived by using relay optics. Not a focus screen...
The SP is my favorite followed by the F2AS. Both Black.
Despite what the article states, the Nikon SP went out of production in the early 1960s. The S3 came back for a brief run for the Tokyo Olympics in 1964. The S3-2000 was introduced in 2000 as a celebration of the new millenia, and the SP-2005 was brought out as a labor of love and pride. I have the S3-2000, but my original SP's are so good, never bought the SP-2005. I've compared them side-by-side (a friend bought one), and the 50 year old viewfinder in mine was just as bright and clear. THAT is a tribute to Nikon. The 50mm F1.4 lens on the S3-2000 is incredible.
