Dianette and Pionette
The Dianette (ダイアネット) and Pionette (ピオネット) are Japanese strut-folders taking 4×6.5cm and 3×4cm exposures on 127 film, made by Fuji Kōgaku in 1936. The two names refer to the same camera, sold as Pionette in Kantō (Eastern Japan) and Dianette in Kansai (Western Japan).[1]

General description
The Dianette and Pionette are copies of the Pearlette by Konishiroku, itself copied from the German Piccolette by Contessa-Nettel. All these cameras were inspired by the Vest Pocket Kodak.
The front standard is mounted on a pair of scissor struts. It has a pivoting brilliant finder at the top right, as seen from the front; the release button and a thread for a cable release are at the opposite side, behind the front plate. The winding knob is at the top right of the main body, as seen by the photographer holding the camera vertically. The back is hinged to the bottom and has a circular fairing in the middle, containing three red windows: a central one for 4×6.5cm exposures and two outer windows for 3×4cm exposures. These are alternatively hidden by an internal cover, switched by a two-position lever: 1 for full-frame, 2 for half-frame. The red window fairing also contains a retractable bead for a wireframe finder, apparently mounted even on the cameras which don't have the wireframe but a frame finder on the side instead.
The front standard is marked Dianette or Pionette at the bottom and there is a logo at the top left.

The camera was advertised in Asahi Camera in March and April 1936 and featured in the new products column of the same magazine in June.[2] The March advertisement gives the price of ¥28 for the version with an f/6.3 focusing lens.[3]
The Dianette is presented in an undated leaflet by the distributor Yamamoto Shashinki-ten.
Kokusan kamera no rekishi reports that the shutter is a Picco giving T, B, 25, 50, 100 speeds (like on the Baby Lyra) and mentions the following choice of lenses:
- Terionar f/4.5;
- Anastigmat Pionar f/6.3;
- meniscus f/8.[4]
Actual examples
Two body versions are known. One is a plain copy of the Pearlette and Piccolette and the other has a simpler design.
Plain Pearlette copy
This body version has a round cut-off on each side and a front plate extending to the bottom, acting as a standing leg. It is the version pictured in the March 1936 advertisement cited above, with a folding frame finder attached to the side plate and offset to the top and the mountain-shaped FUJI KOGAKU logo.
Three examples of this body version are pictured in Sugiyama with the name "Pionette". One has the same finder and logo as in the advertising picture. The lens is front-cell focusing and is reported to be a Terionar f/4.5 while the shutter is reported to be a Picco.[5] Another has a front-cell focusing lens, a partly erased logo and no frame finder. It is reported to have a Terionar f/6.3 lens on a Picco shutter.[6] The third one has a fixed-focus lens marked Fuji-Optical Achromat F=75mm, reported to have f/11 maximum aperure (perhaps by mistake)[7], and a dial-set shutter reportedly called Super and erroneously said to give B, 25–500 speeds. It has a wireframe finder attached to the front plate with an eyepiece attached to the back, and it also has an intricate round logo perhaps written TK.[8]
One example is also pictured in this page at Konrin's Garage.
Simpler body design
The other body version has a rectangular front plate, a retractable standing leg and straight body sides. Three examples are known, all of them called Dianette and sporting the FUJI KOGAKU logo. One is pictured in Sugiyama with a fixed-focus lens marked Fuji-Optical Achromat F=75mm (probably the meniscus f/8 mentioned in Kokusan kamera no rekishi) and a wireframe finder of which one part is missing.[9] The second one is pictured in McKeown with a focusing lens having a wider aperture, perhaps f/4.5, and a folding frame finder attached to the side plate.[10] The third one is pictured in this page of Nekosan's website.
