This sale is for a set of 3 extension tubes for Pentax, Praktica, Zenith M42 mount cameras.

These 3 tubes are in very good condition, having had little use since new.

The linkage provides automatic aperture operation.

The tubes are approximately 8mm, 14mm and 28mm

Using these enables small items to be photographed much closer, & therefore larger on the negative
