The Pupille is a 3×4cm rigid camera made in the 1930s by Nagel, later Kodak AG. It makes 16 exposures on 127 film, has a big helical mount holding the lens and shutter assembly, and a folding optical finder.

The lens and shutter combinations included:

  • Leitz Elmar 5cm f:3.5 with Compur 300
  • Schneider Xenon 4.5cm f:2 with Compur 300
  • Schneider Xenar 5cm f:3.5 with Compur 300
  • Cooke Anastigmat 2inch 50mm f:3.5 with Compur 300

The Pupille has two small holes on the top plate, mainly used to plug an external rangefinder made by Leitz, similar to that of the Leica Standard. Accessory reflex finders were also made, transforming the camera into some sort of TLR. At least two types were available; one is the Megoflex by Hugo Meyer, also made for other cameras; the other is pictured above and was made by an unknown manufacturer, perhaps Nagel itself.

The Pupille was sold in England by R. F. Hunter as the Rolloroy.

The Nagel Ranca was a less expensive version of the Pupille, with front-cell focusing and cheaper lens and shutter combinations.
