At my work someone is offering a Nikkor 55-200mm f/4-5.6 VR for sale at $150.
I have a 70-300mm G (without VR) and it's a crappy lens. It never performs well whenever I see an interesting bird or a far away object. The chromatic abberation is awful and with no VR it's as good as useless for birds. However, the 200mm is not really a whole lot of telephoto... not really enough for birds anyway, but it's a quality lens.
My question is; is it worth getting this lens or should I save my money and put it towards something better in the future?
