If you can see the picture here. This is taken with my new NikonD3100 and I only have to the maximun of 55mm zoom lens. I cannot reach to the goal of grabbing more good pictures from far away. I tried taking up these one and this is the result, too small but not that bad. I am still learning how to use my camera and for now, I don't have time yet to do so. But a friend of mine just bought another lens that can reach up to 300mm (lol) she is not yet a professional photographer but she already explored to the higher lens which is good for her and that is what she want to.
NikonD3100 has a lot of tools that must be discovered and hope to explore them one by one.
