The dependence of T{sub c} on hydrostatic (He-gas) pressure is determined for the recently discovered organic superconductor {beta}'-(ET){sub 2}SF{sub 5}CH{sub 2}CF{sub 2}SO{sub 3} [ET = bis(ethylenedithio)-tetrathiafulvalene] with T{sub c}(0){approx}5 K, yielding the pressure derivative dT{sub c}/dP {approx} -1.34 K kbar{sup -1}. The present experiments also included {kappa}-(ET){sub 2}Cu(NCS){sub 2} where we find the extremely large value dT{sub c}/dP {approx} -3.84 K kbar{sup -1}, in agreement with earlier studies. For both samples the pressure dependence T{sub c}(P) does not depend on the temperature at which the pressure is changed.
