@brittneycase can you add a bit more detail? Do you have a manual focus setting that you have tried? Is this when you try to focus on anything, or is there a particular distance at which this is happening? When you say it won't take the picture, does this mean you have pressed the button halfway down to focus, and press all the way to try to take a picture, and nothing happens?

Yes it has a manual option on the lens and it will take a picture but it's out of focus... And yes when the lens is on auto it will make a scratching sound when it tries to focus and if u push the shutter all the way down it won't do anything... But what is even more confusing is that it's like the camera has bad spells, it will be the best camera ever then out of no where it will start this problem then after awhile go back to being great

When put in manual I turn the ring all the way around and it never focuses.. so does this mean it is a problem with the lens?

That's good to knw about the focus motor.. if it is the lens would that explain why it has this problem every now and then, not all the time? It has worked great all day today..

Hello Brittney,

In the above comment you mentioned that you have a manual focus option and the shot is out of focus... They adjusting the shot using the focusing ring manually (in manual focus mode). When the shot looks clear through the view finder, take the shot. Let us know if it is focused properly.

I am sure you must know how to determine if the shot is in focus... Incase if you don't: when adjusting manually, when the subject is in focus, while looking through the view finder a green light glows on the bottom left corner of the view finder, indicating that the subject is in focus... Take the shot, check if it is in focus...

If every thing works well, and the above shot is in focus, then the possible problems are with the lens (if it has an inbuilt focus motor). D40 lacks an inbuilt focus motor... So camera shouldn't be a problem. (or) problem with the camera and lens contacts... Remove the lens and clean the contact points on the lens and do the same on the camera as well.

I would try the autofocus function using a completely different af lens. Perhaps take the camera to a camera store and try a couple of their lenses in the store.
