We present the results of a study of more than 100 early-type galaxies in Antlia Cluster, that span from giant ellipticals to dwarf ellipticals, covering a magnitude range of 11 magnitudes (M_{V_T} = -22 to -11). We perform surface photometry of these galaxies, and their total magnitudes, surface brightnesses and radii are determined on the basis of the Sérsic law fits. Finally, the fundamental relations between them are analyzed.
