Would this lens fit a nikon D3100? - 1

I just wondered if this lens
AF-S DX Nikkor Lens 18-55mm for Nikon D3000
would fit the Nikon d3100 as i've seen one in the local paper and was thinking if this fits and I get it cheap then I would be able to buy just the d3100 body cheers

Should be D3000 do not have pin for MF but all AF nikon lens work on D3000
look in google

Only Nikon AF-S lenses will auto focus on the D3000, D3100, D5000 and D5100.So yes the Nikon AF-S DX Nikkor 18-55mm zoom lens will be a perfect match for the D3100.

The AF-S 18-55mm f/3.5-5.6 lens is the kit lens that comes packaged with both the Nikon D3000 and the D3100.It is fully compatible with every camera in Nikon's current lineup. I would research the price of the D3100 kit before committing to buy the one you saw in the paper to make sure you are getting the best deal.
If you choose either of those camera bodies, you should note that they will only autofocus with lenses that have the focus motors built into them. To have autofocus capability, you'll need to stick with AF-S lenses.AF lenses are compatible with the camera, but they must be focused manually.
