Recently I became interested in the multicoated E series Porro prism binoculars i.e. those preceding the current EII series
Reading around the topic, I ended up looking at a lot of other information, much of which will be of more general interest . . .
I) INFORMATION FROM NIKON
NIKON BINOCULAR CHRONOLOGY TO 2004
I’ve attached a chronology previously compiled by Nikon. It gives an easy introduction as to when many models were introduced
It was originally posted by elkcub: https://www.birdforum.net/showpost.php?p=2257403&postcount=11
HISTORY OF NIKON
Nikon has a lot of information on it’s website (the product specific information relates primarily to photographic developments): https://www.nikon.com/about/corporate/history/
CORPORATE INFORMATION
Current corporate information can be found here: https://www.nikon.com/about/corporate/
Included at the bottom of the page is a link to a PDF of the 2018 Company Profile, which provides an overview of much of the corporate information
Information about the restructuring plan referred to in the Company Profile - including strategic detail about what is proposed in relation to Imaging Products (which includes binoculars),
can be found here:https://www.nikon.com/about/ir/management/midtermbusiness/ , see the PDF ‘Restructuring plan’, especially pages 20 and 21
II) INFORMATION FROM OTHERS
HANS BRAAKHUiS
A wide variety of information can be found on Hans’ website: http://www.hansbraakhuis.nl/Nikon/Nikon.html
A) Look down the left column to ‘verrekijkers’, and then select the options to the right. These include:
- a comprehensive spreadsheet of introductions and basic detail for binoculars from 1910 on (first for the Fujii Brothers precursors, and then from 1917 for Nikon)
- a history of Mikron miniature binoculars (in Dutch)
- a PowerPoint presentation about Mikron miniature binoculars, based on the above (in English)
B) To the right of ‘Nikon History’ is:
- a detailed history of Nikon, primarily to the end of WWII, and a lot more (in English)
C) To the right of ‘overig Nikon’ is:
- a 1954 Nippon Kogaku catalogue of 22 pages, listing a comprehensive range of products
III) MORE BINOCULAR INFORMATION
1951 MIKRON BINOCULAR FLYER
A flyer for the US market is on the Miniature Binoculars website: http://www.miniaturebinoculars.com/part2/Page21529.htm
The MB site contains a large selection of material about discontinued binoculars
- go to the 3 ‘Research Materials’ buttons at the bottom of the Navigation panel on the right side of the page
1977 BINOCULAR FLYER
The flyer is on the Pacific Rim Camera website: https://www.pacificrimcamera.com/rl/rlNikonNotebook.htm
PRC also has a wealth of old photographic flyers and brochures: https://www.pacificrimcamera.com/rl/rlrindex.htm
pre-1982 BROCHURE
I’ve attached copies of 6 pages from an undated and somewhat worse for wear brochure that I obtained
- based on Braakhuis’ spreadsheet it should date to between 1979 and 1981
n.b. the 1977 flyer above has A series Porro models, this brochure has E series models
1985 BROCHURE
Henry Link has provided various pages with specifications for:
- x50 and x70 Porro binoculars: https://www.birdforum.net/showpost.php?p=2989967&postcount=9
- Action series Porro binoculars: https://www.birdforum.net/showpost.php?p=2307804&postcount=6
- roof prism binoculars: https://www.birdforum.net/showpost.php?p=3282171&postcount=4
(and there is more information about the roof prisms provided by fstop: https://www.birdforum.net/showpost.php?p=3282184&postcount=5 )
- spotting scopes: https://www.birdforum.net/showpost.php?p=1921245&postcount=7
- and an image of E series Porro binoculars: https://www.birdforum.net/showpost.php?p=1897338&postcount=26
ACTION SERIES PORROS (from 1984 on)
Henry has also provided copies of specifications for the various Action series Porro prisms here: https://www.birdforum.net/showpost.php?p=2334547&postcount=22
And some additional images here: https://www.birdforum.net/showpost.php?p=2341566&postcount=30
I hope the above proves to be of interest and use
And as always, if anyone knows of additional resources, please contribute
