in most cases the lens is much bigger of a factor than the camera as far as image quality goes...not counting resolution (there is a noticeable jump from 6mp to 10mp). so you may want to consider that...most people start with a standard/cheapish cameras, build up a nice lens array, then buy a nicer body and use their old body as backup (usually pros do this). but to answer your question yes, they have the exact same mounts.
