Isolette
The Isolette is a compact horizontal-folding camera for twelve 6×6 cm (2¼-inch square) pictures (or sixteen 4.5×6 cm (2¼×1⅝ inch) pictures, with the first model of the camera) on 120 film. It was made by Agfa Kamerawerk AG, Munich, Germany, from 1938.[1] It was the first of a series of cameras lasting until about 1960.

Isolette (1938-42)
First model Isolette. image by Raúl Sá Dantas (Image rights) |
This first model is a dual format camera. It has hinged masks in the film chamber (they pivot around the spindle of the film rollers on each side of the film gate), to change it from the 6×6 cm format to 4.5×6 cm. There is also a mask for the viewfinder, put in place with a selector lever by the eyepiece.
It first came on the market as the Isorette (embossed in the leatherette of the front door/lens bed as JSORETTE[2] ), but the name was changed to Isolette (again, marked on the camera as JSOLETTE) within a year.
One of the distinctive features of the camera is the top housing, made of a plastic called "Trolitan"; the post-War camera has a cast aluminium top housing. This camera also has loops to attach a strap, the only version of the Isolette to have these.
Different lens and shutter combinations were available, allowing a wide range of levels of specification. All have front-element focusing. The shutter release is on the body. Film advance is by a wide, flat knob, using a red window; there are two red windows in the back, one for each film format, and a swivelling cover for the upper (4.5×6 cm) one. There is a swing-out spool holder on the supply side of the film chamber. This model was called the "Soldatenkamera" (soldier's camera) in Germany during the War.

Isolette 4.5 (1945-50)
The first post-War model was made from 1945 till 1950. It is not adjustable to 4.5×6 cm format. The top housing of this model is cast from Hydronalium (Nüral: an aluminium alloy). There were less lens and shutter combinations, offering only the higher levels of specification (no Agnar, nor Vario or Pronto shutters). Most of the lenses are still uncoated.[1] Some of the shutters available are synchronised. The camera has an accessory shoe (above the viewfinder).

- Shutter: Prontor, Prontor-S or Compur-Rapid.
- Lens: Apotar 8.5cm f/4.5 or Solinar 8.5cm f/4.5.

Isolette V, with f/4.5 Agnar and Vario shutter. The upright metal strip at the side of the shutter is the release. Note the control added to offer 'T' as well as 'B' shutter. image by Raúl Sá Dantas (Image rights) |
Isolette V (1950-52)
The Isolette V has Agfa's entry-level f/4.5 Agnar triplet lens, and only low-specification shutters (Pronto or Vario). However, the lens is now coated on many examples, and the shutters are synchronised, with a PC socket. The camera's top housing is now of pressed, bright silver metal: this finish is retained for the rest of the series. The accessory shoe is either on top of the viewfinder or to one side of it (on earlier examples). There is no body-mounted shutter release.

Isolette I (1951-58)
The Isolette I is, like the V, a rather low-specification model. It has a coated f/4.5 Agnar lens, and a synchronised Vario or Pronto shutter. Unlike the V, it has a body shutter release. There are two versions of it:
- 1951-54: the early version has a disc-shaped depth-of-field calculator, mounted in a position matching that of the film advance knob, but on the right of the camera.
- 1955-58: the depth-of-field calculator is now absent; some (but not all) examples have DOF brackets marked on the face-plate of the shutter, around the focus scale of the lens. This model also has a slightly different cold shoe.
Succeeding models
After 1950, several different models of the Isolette were made at the same time, with different levels of specification:
- the Isolette II
- the Isolette III
- the Super Isolette
- the Isolette L
