don't think camera think lenses the camera will change but if you buy good lenses ( L glass for example ) they will stay
iv'e been through the cheap lens faze and it's expensive cos your not going to keep them as you progress
keep the macro sell the other 2 and put the money towards a 70 - 200 L lens which one is up to you that all down to the deph of your pocket
some time in the future buy a 24 - 70 F2,8 L ( great walkabout lens ) a 50mm 1.8 or 1.4 if you have deep pockets and whatever other prime L glass that take your fancy and you will never ask another question about lenses again because you'l have as good as it gets
looking forward to hearing questions about the bodies in the future

oh and the answer is a 1d mk 4
this is written very tongue in cheek but there is some truth between the lines
