Hello I am new here. I have a Nikon D7000 and wanted to ask some questions regarding which lenses to buy. First of all should I buy the Nikon 16-85mm f/3.5-5.6 G ED VR lens or can I buy something better for this price? Second is I right now cannot buy the Nikon 70-200mm f/2.8 so should I buy the Tamron SP AF 70-200mm F/2.8 Di LD (IF) MACRO ? Or just stick to Nikon and buy the 70-300mm f/4.5-5.6G IF ED VR as I cannot buy the Nikon 70-200mm now. Third which prime lens to buy? The Nikon 50mm f/1.4G or Nikon 50mm f/1.8G or the Nikon 85mm f/1.8D AF ? Please help.
