Okay-soI am in the mood (and market) for a new lense. I currently have: Nikon lenses: 18-55mm kit lense, 70-300mm kit lense, 50mm 1.8 I am between the Nikon 18-200mm and the Nikon 105mm Micro (macro). I know they are different lenses but I don't know if I should get the all encompassing 18-200 and sell my 2 kit lenses or if I should add a macro to my mix of toys. I just shoot for fun, mostly my girls, inanimate objects and whatever else captures my fancy. I would love to get a macro lense, mostly to take pics of bugs etc, at the same time, I don't want to ave to lug around a big bag of lenses either. One other question: Tamron vs Sigma vs Nikon? Thanks guys!
