Im heading off to South America as a gap year, and im looking to add a lens. All I have is my trusty D5000 and 50mm 1.4. my budget is about £150-200, although I could try stretch to £250 if there is something better in that price frame, what are peoples views on the Nikon 55-200 f/4-5.6, as this lens fits nicely into my price frame?
