We present results of photometric observations under excellent seeing conditions of Shakbazian Compact Groups. We obtained the seeing-unconvolved surface brightness profiles of individual galaxies in the I band. We also determined the B-I color index for each galaxy, and investigated the presence of cores in the early type galaxies. We constructed models for the mass distribution of the individual galaxies. The mass-to-light (M/L) ratios have normal values, and the conclusion that these groups have little dark matter is confirmed.
