Statistically improved data of total cross sections and of angular distributions for differential cross sections and hyperon recoil polarizations of the reactions γp → K + Λ and γp → K + Σ 0 have been collected with the SAPHIR detector at photon energies between threshold and 2.0 GeV. Here total cross section data up to 1.5 GeV are presented. The opposite sign of Λ and Σ polarization and the change of sign between forward and backward direction could be confirmed by higher statistics. A steep threshold behaviour of the K + Λ total cross section is observed.
