I'm looking for (affordable) lenses for my Nikon D3100. I've had my camera for a year, and have yet to buy a new lens. I'm totally lost in what to buy and would really appreciate some feedback. I've been looking at the Tamron 75-300mm F/4-5.6 LD AF-D For Nikon, but after more research saw that it wouldn't auto-focus with my camera. Any suggestions? Thanks!:)
