The few available data for the reactions [gamma][ital p][r arrow][ital K][sup 0][Sigma][sup +] and [gamma][ital n][r arrow][ital K][sup +][Sigma][sup [minus]] are compared to models developed for the processes [gamma][ital p][r arrow][ital K][sup +][Sigma][sup 0] and [gamma][ital p][r arrow][ital K][sup +][Lambda]. 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.
