Excerpt: The main reason for the Nikon 55-200mm f/4-5.6 AF-S VR DX is the addition of the VR technology, and the first thing that strikes you about this lens is the light weight. At a meagre 355g, its really some achievement to get all it offers into such a small lens. The zoom ring takes up around 2/3 of the length of the lens, while the rarely used focus ring has a tiny space on the front.
Conclusion: The Nikkor AF-S 55-200mm f/4-5.6G ED DX VR delivered a very sound performance with very few weaknesses. The resolution characteristic is generally very good and neither CAs not distortions are something to worry about. The vignetting is a bit more pronounced at 135mm @ f/5 but otherwise not a real problem. The bokeh (out-of-focus blur) is naturally a bit underdeveloped due to the slow max. aperture but apart from this limitation is seems pretty smooth.
