We present results extracting the position of the two Λ(1405) poles from experimental photoproduction data measured recently at different energies in the γp → K + π 0 Σ 0 and γp → K + π ± Σ ∓ reactions at Jefferson Lab. The analysis is done by means of a chiral dynamics motivated potential but with free parameters, which guarantees analyticity and unitarity in the solutions. With the best result we find the two Λ(1405) poles at about 1352 − 48 i MeV and 1419 − 29 i MeV.
