hi there it's compatible for Nikon D3100?

Yes, Sigma makes a Nikon EM-140DG version of this ring flash -- make sure to buy the Nikon version and not the Canon version. It is a good ring flash for macro (closeup) photography and compatible with the Nikon electronics. RS

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

Yes, it will work with the D3000, D3100, and D3200, along with all of the other D-Series cameras I'm familiar with.

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.

Yes it is. You can find a full list of compatible Nikon products in your user manual

I was informed by reading info and some chat that if your model is not listed in the info of the battery it might not work. my wife has the d3100 and it took a little time to find this replacement . good luck, it's out there.

Sorry but don't know. I bough mine for a D80 and a D3100. You have a VERY nice lens!

It should work with the D3100 as well as the adapter fits onto the hotshoe and sends the signal to the strobes. I've used it with the d80 and the D3000 without any problems.I hope that helps you!

It works with the D3100. It's hard for me to believe Nikon changes the basic power system when they change a few features.

Unfortunately I know nothing about the D300 as I have a D3100 and it works wonderfully on the D3100.

https://support.nikonusa.com/app/answers/detail/a_id/16921/~/approved-memory-cards---d3100 says that it **will** work on a Nikon D3100 - however, I do not own a D3100, so I have not tried this (or any other) memory card in a D3100.

Hi Amanda, D300? I don't know. I have a NIKON D3100, and is NOT compatible with. :(

We have the D3100. It appears it should fit, but I don't know for sure.... Sorry about that.

Yes, I use it on a D3100 all the time. But remember, it is a totally manual lens, so your camera will have to be in manual mode (select "M" on your dial). See my review for more details.

NO it does not work with the D3100 - tried it. I had to pass it along to a friend with a different Nikon.

The flash is a generic tool with just a Nikon hot shoe, so it should work on your D3100. I've found it to be helpful. Works better in continuous on mode - either right, left or both.

I am not sure about the D3100. If you already own the camera, I would check the battery that came with it and compare the battery to this one. That is what I did for my D5100.
