The Λ(1405)1/2- resonance is discussed and a fit of the Bonn-Gatchina (BnGa) partial-wave- analysis group is presented to data relevant for this resonance. In the Σπ - NK coupled channel system, no Σ pole and only one Λ pole in the mass range from the Σπ threshold to 1500 MeV is required to get a good description of the data.
