We present the results of an imaging survey to search for gravitationally lensed arcs in a sample of 40 EMSS clusters of galaxies. The lensing frequency obtained suggests that the X-ray selection is the preferred method for finding true, massive clusters which are more likely to exhibit the lensing phenomenon.
