Midnight Sun in the Summer Sweden

The sound of aircraft engines flying over accross the universe.
10,000m high.

I have received some photographs from Mr. Kiril Arsov who lives in Sweden one day.
He took photographs of his owned Historical Nikkor lens.
His photographs were very charming.
The rim of the lens is engraved with "R-Aero-Nikkor 50cm F5.6".

I did not know this lens.
Where was she born? What was she developed?
Is she happy?

R-Aero-Nikkor 50cm F5.6

I examined the lens by the Nikon History 75 Years.
I detected the following descriptions.

The following Aero-Nikkor was made by Nippon Kogaku.

  • Showa 7 (1932) Aero-Nikkor 50cm F4.8
  • Showa 7 (1932) Aero-Nikkor 70cm F5
  • Showa 8 (1933) Aero-Nikkor 18cm F4.5
  • Showa 12 (1937) Aero-Nikkor 7.5cm F3.5
  • Showa 14 (1939) Aero-Nikkor 10cm F5.6 (Wideangle)

I read the Nikon History 75 Years in detail. And, finally, I found the following descriptions.
I got excited.

"Nippon Kogaku manufactured a large-scale aero camera of the name of 'Army Aero Camera Mark 1' in Showa 19 (1944).
This camera is a reconnaissance camera manufactured by the instruction of the Japanese Imperial Army.
Increasing production was necessary, and Nippon Kogaku manufactured one model only by 50cm F5.6 lens. This lens was designed for using by 10,000m high sky.
The large-scale recon camera was an electric controlled. The exposure adjustment and the film wind up were able to be done electrically.
These 600 cameras were produced by Showa 20 (1945) when the war had ended."

Quotation from Nikon History 75 Years, Page 78.

Notes:
Showa is the name of the time span or the Imperial Title of the Emperor Hirohito (1901-1989) of Japan. Years spanned from 1925 to 1989.
Years in Japan are linked to the current Emperor, Hesei in this case.
Currently, 2016 is Heisei 28.

I came to want to know what kind of aircraft this lens had been mounted.
I asked for a lot of experts about information on the recon aircraft of WWII.
I received important information from Mr. Takashi Doi.
Mr. Takashi Doi is a director of the museum, and he taught me the reconnaissance camera.
And, I got to know Mr. nag who is drawing the super illustration of aircraft.
I permitted from nag-san, and published his picture. nag's Gallery

From Kiril-san

R-Aero-Nikkor, landing on the earth.
In Uppsala, the city of science, university centrum since 1477.
A holy place, a church build by the sons of Vikings in 1260. Destroyed by the fire in 1702, and again rebuild, to welcome our R-Aero-Nikkor from the sky.

R-Aero-Nikkor, a piece from the sky on the green field in the middle of the night.
What a strange place, white dreams, the night is bright, all are gone to sleep.
A place for R-Aero-Nikkor from the sky.
