Ron,
Assuming you can a find a close up lens for the G2, how would you compensate for parallex. The range finder has a separate viewing lens, the closer the camera is to the subject, the worst it becomes. If you were say six inches away from your subject, what you see in the viewfinder would not be what your lens would be looking at. In my view, there are two great things SLR's are great for which the range finder cannot do--- macro and long lenses. Within those parameters, you have a wonderful light weight camera with some of the best lenses made for any any 35mm system. Depending upon your subject matter is, that accomodates about 95%-98% of my picture needs.
Good luck,
Howard
