Extension Bellows (Balgengerät)

Several different geared, dual rail bellows were manufactured for the Praktina. The first two versions were manufactured by kW and the third version by Pentacon. The bellows afforded variable focusing in the macrophotography range with extension from 7.7 mm to 55mm (from 10mm on the Version 3).

Versions 1 & 2 Bellows

Manufactured by kW, the first version Praktina bellows was designed to work only with manual or preset diaphragm lenses. (Photo not displayed)

The second version enabled the mounting of the semi-automatic diaphragm lenses (Carl Zeiss Jena Biotar, Tessar and Flektogon) in manual mode. It is shown on the right and you can see the cut out in the mount for the semi-automatic lens aperture cocking lever.

Version 3 Bellows

The third version, manufactured by Pentacon (see the Pentacon Tower engraving) enabled the mounting of all the Praktina mount lenses. Introduced for use with the Praktina IIa, the Version 3 Bellows can also be used with the FX. The semi-auto lenses from the Praktina FX can also be used as can the preset lenses. Rather uncommon.
