Auto Keef
The Auto Keef (オートキーフ) is a Japanese coupled-rangefinder camera taking 4×4cm pictures on 127 film. It was made from 1941 by Kokusaku Seikō and was advertised until 1945 and again in 1946–7.

General description
The Auto Keef has a rigid body and a telescopic tube supporting the lens and shutter assembly. This telescopic tube is mounted on a focusing helical, coupled to the rangefinder by a pinion. The range- and viewfinder is combined in a single eyepiece and is contained under a top housing. The square viewfinder window is in the middle. The camera has auto-stop film advance, a necessary feature because the paper backing of 127 film is not marked for 4×4cm exposures.
First model
The first model is only known from an advertisement dated September 1941 reproduced in Kokusan kamera no rekishi[1], perhaps depicting a prototype. The advance knob is on the right and the round rangefinder window is on the left (as seen by the photographer holding the camera). It seems that the name KEEF is engraved above the rangefinder. There is no accessory shoe and the position of the exposure counter is unclear. The rangefinder coupling pinion is on the right (same convention) and it is apparent and not hidden under a housing.
The release button is placed atop a large housing protruding on the right (same convention) of the shutter casing. The lens offered in the advertisement is a K.O.L. Keef 60/2.8 and the shutter gives 1–500 pictures. The advertisement wears the name of the maker and the name of the distributor Kazenderu Shōkai (カゼンデル商会)[2].
Second model
Advertising
The top housing, marked Auto Keef, covered the combined range and viewfinder, with the square viewfinder window at the center and the second image round window at the right. There was an accessory shoe offset to the left and the small exposure counter window at the extreme right. The rangefinder coupling mechanism was covered by a tortuous plate, with PAT. P. markings and the Keef logo repeated twice. The shutter release was mounted at the bottom right of that plate.
A 1942 ad (shown here, from Asahi Graph, 23/9/1942 issue) listed two models:
- Auto Keef I, K.O.L. Keef 60/3.5 lens, 1-200 shutter (223 yen)
- Auto Keef II, K.O.L. Keef 60/2.8 lens, 1-500 shutter (264 yen)
On the ad's picture, the shutter plate is marked KOKU SAKU on top and KEEF at the bottom.
Actual examples
Observed lens/shutter combinations:
- K.O.L. Keef 6cm f/3.5 lens (same handwritten style K.O.L. marking as a lens observed on a Gaica) & T-B-1-300 shutter (300 at left) marked Kokusaku (for sale at a Japanese dealer)
- body s/n 2961, lens reported as a Tokyo Kogaku Toko 50/3.5 s/n 52679 (focal length seems dubious) & T-B-1-250 shutter (250 at right) reported as a Keef II (Leski auction #191)
- body s/n 2234, lens reported as Tokyo Kogaku Toko 60/3.5 s/n 51828 & shutter reported as Keef Koku-Saku (Leski auction #223, #249 & #270)
