Re: 105mm f/1.8 or 105mm 2.8 VR ?
Hi:
I have the 105 f1.8 lens, but not the new VR. My only observation is that these lenses are remarkably different in both purpose and capability.
If you can afford to have a specialty lens or two waiting around for the right moment, get both of them. One is a particularly good longer portrait lens. In the days of manual focus cameras using full frame 35mm film, 105mm was a popular focal length for head and shoulders fashion portraiture, and the f1.8 lens was really very good in that role. For reasons that elude me, the 105mm f2.5 was always more popular with Nikon SLR users -- amateurs and pros alike.
The f1.8 did not sell well in the old days, despite being very sharp even wide open (and very good at the edges), and very fast for 105mm lenses. But with the DX format, the wider f1.8 f-stop becomes relevant for helping to blur the OOF areas to a more creamy texture. And the edges are closer to the sweet area of the lens in DX format, too. Of course, the f1.8 is a manual lens (with a clunky built-in hood).
As for the new 105mm VR, not only does it do macro work, but also it is AF-S, and has VR. It may be too sharp for some portrait work, but if you like extra-sharp images, you probably will not go wrong. It's main design is not aimed at portraiture; it is aimed at macro to middle distance. I have not seen any shots at infinity to tell you how sharp it is out there, or how fast the motor focuses at infinity, despite being geared for close-up work. You can use it for hard-to-focus fast moving subjects because of the AF-S, and you can use it in low light handheld for static subjects because of the VR II. These are unique qualities, but may not be what you need if you decide to use it for straight potraiture.
The new lens is by far the more versatile, given all of its capabilities. But, this is really a different animal from the f1.8 AI-S, which may be your best choice of the two for portraiture, expecially of men who can benefit from this long-ish focal length for DX portraiture. For female and child portraits a shorter focal length of 85mm or less may be a better choice than either of the two lenses discussed here.
Personally, I'd get both. I certainly plan to pick up the 105mm VR, but mainly for macro and short distance images to supplement the 60mm micro, also a very good lens.
