Would this work for the D40?

Just make sure you select the right manufacture. For example if you have a canon make sure you buy the lens for the Canon body. With that said this is an all around great lens

I don't own a 40d, but a 40d has the same lens mount as all the other eos canon dslrs, so there is no reason it wouldn't.

It fits d40, but the autofocus will not work. This is probably not the best lens for your camera.

I believe it will. Mine worked with a D90, a D60 and a D40 so I assume it should work with any Nikon DSLR mount.

Yes. I bought this for my D40x and upgraded to the D7000. Works great for both cameras.

This lens will fit your Nikon D40, but it is based on the filter thread of your existing lens. If you have a Series 7 or 46mm lens thread, this will fit directly. Otherwise, you may need an adapter ring.

This will not fit a 40d. It takes compact flash type cards and this is an sd card.

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

The writeup says it will fit your d40. I use the k1000 lenses With my D3100 and it does what it is supposed to do. Just remember that the lens will be manual only and you need to adjust for the added focal length.

I've got one on an older D40X. I'm pretty sure it is compatible with the standard D40.

Yes it will. It will work on any camera system but the "C3" portion of its model number indicates that it will also come with the appropriate cable or it to work as a wireless shutter release also on the 40D.

The question was: compatible with NIKON D40 (not D50). USeful information but not directly to what was asked...

Autofocus works fine on my D50, so unless the D40 is fundamentally different, it should work just fine.

No, this remote is for cameras that have a 10-pin nikon remote connection. The D40 does not have a 10-pin connection.

I am sure that It will work. I do not own a Canon 40d, but if it takes as standard SD cards it should work. I have used it in a go pro hero 2, Nikon 1 and Olympus EPL 3.

Hate to give you the wrong answer but By checking on your it looks like Yes it will work, not sure about the flash but it will work. The details on the bracket seems like it would fit the entire equipment or at least the original. It did work my D40 nikon, I will suggest to write the model on google or even amazon and see if it fits your cam. Let me know later how it went.

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).
