So I've been learning photography for couple of years and I've consciously tried to concentrate on fundamentals instead of gear and I've been shooting on old Canon t2i. But now I would like to start actually building my fashion photography portfolio and get models for ModelMayhem and I was just wondering, what kind of cheap camera you need at for minimum in order to not to be laugh at by those models? I don't have much money but I don't want to come off as total amateur.
