The few available data for the reactions γp→K0Σ+ and γn→K+Σ- are compared to models developed for the processes γp→K+Σ0 and γp→K+Λ. It is found that some of these phenomenological models overpredict the measurements by up to a factor of 100. Fitting the data for all of these reactions leads to drastically reduced Born coupling constants.
