Lenses for my D3100

[peter212693]

Hello all,

Im looking to get a new lens or two for my D3100. I currently have the kit lens 18-55mm. I was looking at a 70-300mm telephoto/macro lens for sports and macro, are they any good? Or do I need something different, it would probably be a sigma or tamron.

Also thinking of a nice F1.8 lens, either 35mm or 50mm for portraits. Which would work better on my camera?

Im new to all this so be nice

Thanks for your help
Pete
