So I have a Nikon D5100, with the simple 18-55mm lens that it comes with, however I need a lens upgrade. I'm not an expert when it comes to lens, but I want something with a far zoom as well as nice focus. I have no idea what lens I should get, but I don't want anything about $500 or $600.
Sigma or Tamron 70-300? I use the tamron one, and it gives quite good results (to me, with a D60) it also depends on what kind of photos you want to make.
Can I get some help with this, please?
