Would this lens fully work with a Nikon D3100?

Yes it would. I have a Canon crop factor (ef-s) camera, and the Nikon that you are using is also a crop factor (DX) camera. Just remember to order the Sigma lens in a Nikon mount. Sigma, has only made this lens in a crop camera mount. So it will never work on Full Frame cameras. Have fun, good luck.

Yes. Just tried it on a D3100 ... works fine. I believe it works on most Nikon DSLRs.

No this lens doesn't have a built in motor to focus so it relies on the camera body to focus. The D3100 doesn't have the auto focus motor on the body like the D300, D700, etc. You could use it as a manual focus though on the D3100.

I don't know; I bought this for a Nikon D3000, please check with the seller to see if this will work with a D3100.

Don't see why not. It works with my D3100 and they are basucally the same camera with slightly different optics.

Yes, you can use this lens on the D3100 but only with manual focus. Hope this helps.Blue Penn Cameras

Actually no; the lens certainly will fit on your D3100 but the camera won't know it is there unless you put it in(M) manual mode, and then the TTL lightmeter won't work. Only CPU lenses work with the D3100 or D3000, or D5000, and D5100

Try www.kenrockwell.com., you can look up the lens & find out if it's compatible with your D3100.

It sure works on the D3100. I don't know why it wouldn't work. Take your camera to the dealer and ask to try the lens. That way you will know.

Based on the info I have, it may work with D3100; but will not work with the D40, D40x, D60, and F3 (they can't autofocus with it).

If yours came with the 18-55mm AF AV lense then it should. With the AV featured turned on vibration is minimal. My hands a failing so I went with the D3100-I can't really see shaking. I am not a pro. If you get it enjoy. This is the lense of choice on my Nikon; it starts where the 1st lense leaves off and gives very good telephoto capability.

I have the D3100 and it works fine, I am relatively sure this will work on all Nikon DSLR's

I believe it does I have the D3100 and it works with that, they are almost the same camera.

It works with my D40X and my D600, so I imagine it would work just fine with the D3100. And yes, it is a motorized auto-focusing lens.

I use it on a D3100, and it works fine. The two are similar in shape, but I wouldn't stake my reputation on it. Take it to a shop and compare.

You need to check the specs of your camera to make sure that this lens is ok.for example: D7100 is ok but not D3100.

I bought this lense and it works fine with my D3100 so as long as the connection ring betweeen your and my camera is the same it will be compatible.
