does this work in a d3100

Yes, as long as it is the Nikon version. The Sony or Canon versions will not work with the D3100.

I have the D3100 and it works fine with my kit. According to the Nikon website, both the D3100 and D7000 have standard 1/4" tripod sockets, so I would bet it would work with yours.

I have a D3100 and it works perfectly! It does say it's compatible with the 7000, so I think you're ok

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.

I have the D3200 and it works with it. Can't say about the D3100, but I would think it will.

Yes, it has an internal focusing motor so it should be fully compatible. I have a D3100 and it works fine.

I don't know if it will work for the d3100 or not. I got mine for a canon, hoping it would work but unfortunately it doesn't.

It works on my D3100, so I would assume yes, but the adage over making assumptions applies but really the only major differences between the two was image processing and megapixels I believe. It goes into the top port on the 3100 (pic http://www.dpreview.com/reviews/nikond3100/Images/ports.jpg) and looking at a similar pic for a d3200 (http://www.ephotozine.com/articles/nikon-d3200-dslr-review-19230/images/highres-nikon_d3200_ports_1338215617.jpg) that port is still there just at the bottom (under the rubberized cover on the left side)

It sure will work, but you are gonna have to use manual focus because d3100 doesn't have its own motor, just like this beautiful lens

If there is a mic outlet on the 3100, then yes. I have the d7000 & it works perfectly.

I don't know for sure, I have the d3100 and it works so I would guess yes. I have not had the problem others have had with it getting stuck in the camera, but it is annoying that I have to take the batteries out when I am not using because there is no power button. I would buy it again though If I were to go back in time, very handy!

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).

This Tamron AF 17-50mm lens has internal focus motor, so it should work with D3100.

This worked for me in a d5200, so I don't see why it wouldn't work with the d3100. I haven't had any issues with it. Great purchase!

Yes. I own and use a d3100. The lens fits and works. It is manual focus though.
