I'm sure that the optical quality of Nikon lenses has gone up quite a bit with many of their AF lenses. Of course, you might question the mechanical quality if you look at their consumer zooms, but nothing is wrong with the pro-type lenses. Nikon lenses are going to be a lot cheaper than Contax because they are mass-produced for the world's professionals whereas Contax is only used by a handful of serious amateurs.
If you are interested in a macro lens and an 80-200 zoom then I don't think you are a very good candidate for a rangefinder camera like the G1. Speaking of the 80-200, the Nikon 80-200/2.8 D is probably one of the best in the world.
