Do you know if this lens will fit the Nikon D40?

I have no idea. I'd call Nikon. They say that old Nikon lenses will work with old Nikon cameras but theer may be limitations.

If your lens work well with D40 directly, this macro lens will work with your lens.

It depends on the lens. For my D40 I use a 52mm cap. For yours just check the writing on the lens, look for this symbol Ø, and the number to the right of it is your lens cap or filter size in mm (filter thread size, or whatevs).

Well I bought it for my Nikon D5100 and it works perfect. I am not sure if it works for D40. Thanks Betty.

Lisa, Look on your lens, it will tell you what size it is. If it is a 52mm then the macro lens here will fit it. If it is not 52mm do another search on Amazon and you will find the proper size macro lens for your Nikon. :)

I can't answer that from experience with the D40, but my guess is that yes it would work; most all of the Nikon lenses are compatible. Be forewarned that it is a heavy, heavy lens.

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.

It fits the Nikon D40 kit lense, and its a 55mm so I am sure it would! 55mm is 55mm

I don't know. Go to the manufacturers website and research. If it will work with a D40, it should work with a D3000.

Good luck getting info from Nikon! I tried via their site and got nothing. I would think the lens will fit, though

I would check Nikon's website for compatibility. If I can get my 30 year old manual, film-based Nikon lenses to work with my digital D-40X, I would think this newer lens should work with a newer Nikon digital SLR - Nikon is pretty good with compatibility and they are currently advertising even more modern Nikon SLRs with the same 55-300 VR zoom lens.

if you get the 42mm to 58mm adapter it should work IF Nikon did not change the lens thread on the lens. Look and it should say size, ie 42mm (or it might be 46mm I don't remember rightoff hand but the threadsize is marked)

I purchased this lens to use as a flexible architecture and portrait lens on my Nikon D90. The lens did not autofocus when on my DSLR, and I had to return it. This may have been due to a defect in the lens, however. I hate to encourage buying something just to see if it will work for, only to have to return it, but if you have no other way to confirm that the lens works on your D40 then you may have to do that. Best bet would be to contact Tamron directly to ask them.Good luck!

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.

I hope you found it by now or otherwise got the Sigma version but the newer version of this lens marked "with built in motor for Nikon" will autofocus on the D40/D40x/D60. I just ordered one through an amazon warehouse deal and am anxiously waiting its arrival. Here's a link to the newer 17-50 you would want for your D40x:Tamron SP Auto Focus 17-50mm F/2.8 XR Di-II LD SP Aspherical (IF) Zoom Lens with Built In Motor for Nikon Digital SLR

it should, mine came with an adapter that allowed it to fit my Nikon. Pain in rear if you want to switch lenses real fast, but great lens especially for the cost
