Just to throw in an idle comment, but the Nikon 105/2.5 is famously sharp, a stop and a half faster, and probably lighter, than the zoom you're looking at. It's also relatively inexpensive on the used market. This is why I haven't bought another zoom for my cameras, though there are times I would appreciate not carrying a second lens in my pocket; primes are just faster for the weight, and sometimes you need that stop or two.

Just for reference, KEH lists an AI/AIS 105/2.5 for ~ $100, or a 104/4 MicroNikkor for ~ $150.
