will this Auto focus with a D3100?

YES...... I would highly recommend this lens and it is now used as my general lens of choice. To use the macro, it is necessary to stand back further than most lenses but it still produces a very crisp image. The weight of the lens helps to keep the camera steady as it is weighted well making the whole unit more sturdy. So far I have no regrets.

It fits on the D3100, and you can take pictures with it; but nothing automatic works with it so it doesn't autofocus, and it doesn't TTL light meter; only CPU lenses work.

It will work with the d7000, not sure about the D3100 It's a full frame lens

No, it is not compatible with the D3100. It is however compatible with the D3000 and the D3200.

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

Hi, I have a Nikon d3100 and this thing was so hard to have it work. besides that you have to manually set the F number before you take the lens off to attach the tube. it was a hustle and had poor quality. I ended up getting one that was around 50 bucks,my advice? save up and get the one that can auto focus

Hi, Buddy, it works great with my D3100, as a remote shutter as well as flash trigger.

Yes, your camera has the autofocus motor ('screw drive'), so you will have autofocus on with this lens on your body. There is a newer version that will work with the basic nikon models (d3100, d3200, d5000, d5100, etc).

Yes--I use it for my D3000 and it works wonderfully! (You can't use auto-focus with it... but I HATE auto-focus, so that's not a problem for me.)

Yup, if you're comfortable using manual focus this will work with your D3100. With that said, I'd probably put my money towards the 35mm 1.8 (Nikon 35mm f/1.8G AF-S DX Lens for Nikon Digital SLR Cameras). It's more expensive and can be a little hard to get your hands on, but it will auto focus with the D3100. However, if you want a great lens to shoot static images (product shots, nature shots, even portraits) you really can't go wrong for the price. If you plan on taking candid pics of your kids or other non-posed pics, expect to loose some nice shots while you're trying to manually focus.

it works on the 3100 but will not auto focus so it should work for you without auto focus

Yes but the autofocus won't work because the d3100 doesnt have a build in motor .

Yes it does work with the Nikon D3100, we purchased it and have enjoyed its functionality. One thing to remember is that this lens does not have automatic focus.

It will work but as a manual focus only. The 3100 doesn't have an autofocus motor so it depends on the lens to have one built in. Your autofocus will work with any lens that has "AF-S" or "AF-I" in the descriptor, but this one is just "AF". Otherwise, you will get beautiful photos with it, but you have to manually focus. Also, because of the crop factor of the smaller DX sensor, this lens will become a 35mm lens for zoom purposes. Sadly, the only 24mm prime lens Nikon makes that will autofocus on the D3100 is a pro lens that will cost about four times what the camera did. Don't be afraid of manual focus, it's faster in low light and with a lens this wide, it's very forgiving so you can get sharp shots in a hurry even at f/2.8.

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.

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

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