Combo for my nikon D3100?

I'm using an 18-55 for my d3100. I want to buy a new lens. I'm choosing between the DX 18-105, DX 55-200 or Tamron 70-300? Any suggestions please.

I have the DX 18-105 lens for my Nikon D3000, and i can confirm that it is a wonderful lens offering a brilliant upgrade from the 18-55, so if i were you I'd start with that.

It all depends on what your looking for. The lens' you have listed are no better than the other except for the focal ranges. If your looking for a zoom lens the 55-200 would be good, in combination with yours giving you 18-200mm. The 18-105mm came with the d90 which is also gives a good range of play without needing to change lens'. Your choice.

I've read bad things about Tamron lenses. I purchased a Sigma 70-300mm with a Nikon motor and have been happy with that. I use the lens for most of my photography because the longer lens doesn't compress the image.http://www.amazon.com/gp/product/B0012X61U2/

For my next purchase I'm looking at an 18-200mm lens. While the 70-300mm lens is nice it's difficult to work with in small rooms.

It really depends on which Tamron 70-300 we're talking about. The VC version comes close to the Nikon 70-300mm IF-ED VR, but the normal version isn't work writing about.

May I also ask what do you really need with the extra reach of a telephoto lens? I can see the use of the 18-105, it's quite a handy lens, but beyond, say 135mm there isn't any use to get a cheapy lens.

If you're shooting wildlife or sports you need something a whole lot more serious, a Sigma 150-500 or perhaps a 300mm f2.8 if you've got the funds. Otherwise stick to upto 135mm.

I'd get the Nikon DX 55-200VR. The 18-105 is a lot of money to cover most of what you already have. I used to have the 55-200 VR, and it's a superb lens for the price! It's super sharp, and very practical, as well as cheap!

The only reason I don't have it anymore is because I traded it in towards a 105mm f2.8 Macro for my D90.
