Reviews on this lens please. I am going to a wedding next month and was requested to take some amateur shots. I only have the stock 18-55 kit lens. (Nikon D40). Considering purchasing: Tamron Zoom Telephoto AF 70-300mm f/4.0-5.6 LD Macro Autofocus Lens Thanks! COMPARE WITH: Nikon 55-200mm DX AF-S Lens Nikon 70-300mm G Lens Nikon 18-200mm DX AF-S VR Lens OR any other wide angle-telephoto zoom lenses with a budget of MAX $200.
