will this work with a Nikon D40?

I'm not 100 percent sure but it says it should work on any 67MM or 52MM lense. If you use the standard lense there shouldn't be a problem with it.

Yes, any 52mm lens (which the D40 will have if you're using the kit lens). One word of warning, there will be a slight blurring at the left edge of the picture. It's nothing bad that I would discourage people from buying this, but just a warning for perfectionists. It's still a great investment to digitize a large amount of slides quickly for fairly little money (although it was only $30, when I bought it). If you are concerned about the severity of the blurring, just look at the pictures I posted in the "customer images", the 1950 and 1951 Kodachrome slides. You probably won't even notice the blurring unless your subject is in the extreme left of the slide. Yes, any 52mm lens (which the D40 will have if you're using the kit lens).

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.

I am sure it will. I use it with a D800 and it works great. I would also mention there is a fully functional trial available through Nikons website. Once you decide to buy, just enter the serial number from the disks and you are set without reinstalling.

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

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

I have the Nikon D7000 and it works perfectly, so I would think it would work with yours.

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

The short answer is yes it will but it won't be an 85 mm lens on a D40 it will be a 85 x 1.4 (correction for sensor size) = 120 mm f/1.4. Heres some reference info for future consideration - https://support.nikonusa.com/app/answers/detail/a_id/16436/kw/D5000/r_id/116678

I have no idea, I am afraid.I do know it will not work with most Nikon digital SLR's.

Bruce, yes it will work in your Nikon D40. These are great SD cards and they are fast enough to capture several photos per second. Hope that helps.

I can't say for sure. I would think that if your camera has a standard Nikon mount, it should. I have the low end D40, works like a charm.

I doubt it, did not work with my Nikon which it was advertised to do so. Save your money.

It is compatible with both the D40 and D40x. Below are from the D40 tech specs: Optional Accessories: ML-L3 Wireless Remote Control, Capture NX, Camera Control Pro, EH-5 AC Adapter, EP-5 AC Adapter Connector, EG-D100Video Cable, Semi Soft-Case CF-DC1, Speedlight SB-800/SB-600/SB-400/R1C1 From: http://www.nikonusa.com/template.php?cat=1&grp=2&productNr=25420

Don't believe it will...it has to plug into the 10 pin propietary plug that some of the Nikon cameras have. My old D70 doesn't have it but my new D800 does.

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).

Not certain. It may fit, but have no auto focus. It is also a full frame lens, making it heavier than most lenses that are used with your D40.
