I am looking at a Nikon AF-S DX 18-200 3.5-5.6G ED IF VR & a NIKON 12-24mm F:4 G AF-S DX. I am trying to capture wonderful pics like some of the ones on here and wanted to make sure I could do that with these lenses. Also, what do you guys think about the 55-200 VR? Thanks in advance. BTW, I have the 18-105 right now.
