Is the Contax G2 in the same league as the Hexar AF, in AF alone? I've had the Hexar AF and I had no complaints, but I'm thinking of getting a G2 because of the higher top shutter speed and the 45mm lens (I prefer 45mm-50mm over 35mm). I understand that I am compromising the viewfinder, which is maybe a bigger problem, but in terms of AF the G2 should be no worse, right? Or is it? The main difference between the two seems to be the viewfinder, ergonomics, and the interchangeable lenses. Price too, I guess, but I don't consider the difference to be that substantial.
