Pros: Excellent image quality, excellent build, excellent VR implementation
Cons: pricey, shortens focal length when focusing close, max aperture goes down to f/4.8 at closest focusing distance
Impressively, the Nikon 105/2.8 VR shows center and corner sharpness through the entire aperture range. The sweet spot is said to be between f/5.6 to f/11, but inspecting 100% crops did not reveal much loss of sharpness at the larger apertures. This probably has a good deal to do with the ED glass element and Nano Crystal coating showing its worth, but it is also probable that the lens outresolves the 6-megapixel APS-C sensor on the test body (a Nikon D50), so any decrease in sharpness is not as apparent.
Likewise, color and contrast are also consistently well rendered through the range of apertures. The only flaws in this gem are flaring and chromatic aberration, which shows up in high contrast scenes from maximum aperture (f/2.8) and is minimized by f/5.6. This is, however, typical of many large aperture lenses at maximum aperture.
Bokeh is one of the best traits of this lens, pretty much up there with some of the best Nikkor lenses, like the 85/1.4 AF-D. Out of focus areas are smooth, and the 9-bladed diaphragm helps to render out of focus point lights as circles rather than harsh geometric shapes.
