We have studied five seasons of OGLE-III data for eight SMC Be/X-ray pulsarsfor which no other survey data were available. We have determined orbitalperiods for four of these binary systems, one of which also shows nonradialpulsations. Optical identification of SMC X-2 is reconsidered, but no periodswere found for either of the two possible candidates
