In parallel to charm hadroproduction the experiment SELEX (E781) at Fermilab is pursuing a rich hyperon physics program. SELEX employs a 600 GeV/c beam consisting of 50% {sigma}{sup -} and {pi}{sup -} each. The three-stage magnetic spectrometer covering 0.1{<=}x{sub F}{<=}1.0 features a high-precision silicon vertex system, broad-coverage particle identification using TRD and RICH, and a three-stage lead glass photon calorimeter. First results for the {sigma}{sup -} charge radius, total {sigma}{sup -}-nucleon cross sections, and a new upper limit for the radiative width of the {sigma}(1385){sup -} are presented.
