Nikon AF-S DX NIKKOR 17-55mm f/2.8G IF-ED Lens

This is the lens to get for your Nikon Digital (except the D3) Silent wave motor, ED glass, 77mm thread (same as most other Nikon Pro lenses) great range 17 (27mm) to 55 (80mm)awesome build quality though you must take into account its heavy (you combine it with a D300 a grip and a flash and you are lugging around quite a weight) I use it for wedding photography with great success very rarely having to reach for another lens. the only thing that causes this lens problems is the much cheaper Sigma 18-50mm 2.8 - this lens is just as sharp! Though the build quality is distinctly lacking however if you compare pricing on Ebay £210 for Sigma vs £500-£600 for Nikon you can see that it might be worth trying the Sigma first....
