The Nettax fits between the Super Nettel II, with which it shares a body housing and shutter, and the Contax. When first shown in 1936 at Leipzig it was listed as the Super Nettel III, it was aimed at those who liked the Super Nettel but wanted interchangeable lenses and were not able to afford the more expensive Contax; with an f2.8 lens the Nettax cost £32 compared to £43 for the Contax II.

Unfortunately the Nettax was not developed and its range of accessories remained limited. Standard lenses were either an f2.8 or f3.5, 5 cm Tessar, a 10.5 cm long-focus was available and the Contax 28 mm Tessar wide-angle could be used via an adapter (without rangefinder coupling).

The rangefinder used is a rotating wedge type similar to that used on the Super Nettel, the wedges are contained within the lens mount and coupled to the focusing lever that surrounds the lens.

Early illustrations show a camera without a red spot on the body to align the lens and without the fold-out foot, possibly a pre-production model.
