This will not attatch to the camera itself. It is like a filter that you can attatch to your lense. It includes a few adapter rings that will fit a few different lenses.

I used the kit lens off my D40 and it works fine. It should accept any standard Nikon lens.

It worked great for my Nikon D60 which also has an 18-55 lens (the lens that came in the kit with the camera) so it may work on your Nikon D40x. It is worth a try anyway.

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).

It should be compatible with all Canon mounts. I don't know whether the 40D has IS, so you may want to double-check that before buying. It will still work and might be worth having for future compatibility (I had an IS lens with my 20D for a long time, but wasn't able to use IS until I got my 7D).

The Sigma site says that this lens is compatible with Nikon D40. The autofocus and auto exposure should work well. I use it on a D5000 and have been very impressed with the lens.

Yes. I have the D40 and use this all the time. You need AF-S lenses for the D40.

Yes, this will work just fine. I actually have it on a D7000 and am very happy with the results.

Yes I'm using this with a D7000 and it works perfectly, nothing else required.

Thank you for your interest in our bundle! This is fully compatible with your Nikon D40. However, this lens only works in Manual Mode and Focus only. You will lose automatic abilities.

This question would best be answered by Pixel`s web site. If my memory serves me correctly, I do not think it works with the D40. It may work with a software update but not sure.

This adaptor should work fine with the D-5000 and D-600 Cameras. I used this adaptor with my D40X, but found the quality of my shots were not very good. I did return it. Some reviews on this adaptor indicated that it produced good results some did not. My experience was out of focus and milky.

HI. I do not have a D40, but I believe it is a DX like my D7100, and it should work fine. The 10-24 is a great lense!

It works fine with my Nikon D7000. With the same hotshoe configuration for all Nikon DSLR, I believe this should work with D3200 as well. But worth checking with the manufacturer, IMO.

It should work fine on a D40. I've been using it on my D70 have had very good results. It definitely is not built to be used as a lifetime investment, but I have had mine for a few months and haven't had any problems.

Should. I use with D7000. Remember, it's heavy. Takes some getting used to.

The Nikon version of this lens will work with just about any Nikon camera, but there is no such thing as a D4000. I don't know about Sony compatibility, but I do know that the Sony version will not work on a Nikon, nor vice versa.
