The reason I questioned if you needed a macro lens is because you stated that you did not really want to go to 1:1. The 50mm f1.8 is about 1/3 of the price of the Nikon 60mm macro, so if you want to try this focal length, but are'nt sure, this would be a cheap way to find out. The 60mm is, no doubt, an excellent sharp portrait lens as are most macro lenses.

Actually I would occasionally like to go down to 1:1. The new 60mm Nikon is the sharpest Nokon Macro ever. In fact Tamron, Sigma and Nikon lenses are all seem to get at least 4/5 ratings, so you can't really pick a bad lens.
As a portait lens the Tamron 90 is probably a better focal length than the Sigma 105. Comparing the Nikon 60mm vs 105VR, the 105VR has a better working distance for macro work and allows non-tripod Macro shots with its gain of up to 4 stops image stabilsation, but is more limited for indoor portraits. Thom has a comparison on the Nikon 105VR and Tamron 90
here and he seems to prefer the more expensive Nikon lens.
So I think my preference order is now:
- Nikon 105mm f/2.8G ED-IF VR
- Tamron SP AF 90mm f/2.8 Di
- Nikon 60mm f/2.8G ED (the new 60mm)
The 105VR appears to have a lot more flexibility as a "walk about" lens.
