Question about Nikon D40x Digital Camera

1 Answer

My Nikon D40x won't auto-focus. When I press down the shutter button, it won't do anything at all. If I switch to manual and back to auto, it works for 2-3 shots, and stops working again. If change shooting modes from single to timer and back, it might work for a couple shots. I have not been able to find any other solutions. Any suggestions?

    Dirty contacts are most unlikely to be temporarily improved by simply changing the mode dial, so I suspect the problem is elsewhere. Do you get this problem with all lenses or just one? If you have no other lenses you're going to have to borrow one to find out. Maybe you can visit a camera store and pretend to be interested in buying a new lens. Of course, you'll have to try it on your camera body in the shop to see whether you like it...

Try cleaning the contacts on the camera body and lens where they meet with a cotton swab lightly dampened with rubbing alcohol

My Nikon D40x will not always take a picture when I push the shutter and will not focus whats wrong with it?


I have the same problem and I make this: take out the zoom lens from the body and put it again. The auto-focus comes back. Another my solution: Push autofocus buton to M (manual) and back to A (auto). Then sometimes starts again to work autofocus. But still I know it is not final solution...

Autofocus problem


Does this problem still exist when you have the shutter pressed halfway down?

It won't take pictures sometimes. push the shutter button and nothing happens.


The Nikon D40 in Auto Focus mode will only allow the shutter to operate when the image is in focus. When looking through the viewfinder, the bottom edge provides information relative to what you are looking at. See the image below:

Item 2 is the focus indicator. It must be illuminated to allow the shutter to release. If it is not illuminated, the lens has not been able to determine the correct focus. This can happen when attempting to take a picture in low light conditions. Make sure that the front facing "focus assist lamp" on the camera (between the shutter release and lens) has not been blocked or disabled (Settings Menu # 09) and try again. Many times, you will see and or hear the lens "hunt" for proper focus - the lens will travel from one end of its focus range to the other trying to find focus. When it can't, it stops and prevents the shutter from releasing. You can get around this "unable to focus" issue by changing the position of the switch on the lens to "Manual Focus" mode, detailed below:

If a lens has an "A - M" switch, move it to "M" to manually focus. If the switch says "M/A - M " then leave on M/A (unless you're going to be taking several or more in manual mode), as these lenses may be focused manually at any time in either position. As soon as you tap the shutter button in M/A you return to autofocus.



More advanced lenses, like the 18-200mm, 70-300mm VR and 18-135mm, and any lens with an M/A position, may be focused manually at any time without moving any switches. Leave them in their A or A/M positions.

I hope this helps and good luck!

I have turned camera on and set up to take a photo and the shutter release button will not press in to take the photo. I used the camera yesterday and it worked fine!


Turn the camera on and look into the view finder while you try to press the shutter button. Check the information in the view finder to see whether you are getting an error message. If you see an error message in the view finder, remove the lens cap and proceed to take a photograph but, instead of pressing the shutter button this time, press the button near the top of the camera on the back which says "AF/AE. If the camera takes the photo it means you have somehow initiated the auto focus/auto exposure lock which the camera will not override when attempting to take a photo using the shutter button. When you use the AF/AE button, you override this system. To remedy this issue, when you get the error message try pressing the shutter button again. Also, remove the lens to see if the shutter inside has frozen in the "locked" position. If you find this to be the case you will need to contact Nikon Customer Support. The link for Nikon Support is below. The numbers are half-way down the page.

Automatic focus not working


The D40x only autofocuses with the latest AF-S (and old professional AF-I) lenses. Most traditional (screw-type) AF lenses from 1986 through today will not autofocus on the D40x. If your lens says "AF-S," you're fine.
Most lenses sold today for the D40x are AF-S, and so is the included 18-55mm kit lens. Many non-Nikon lenses from Tamron, Tokina, Quantaray, Sigma and anyone other than Nikon still won't autofocus on the D40x. Try before you buy, but honestly, there isn't much the included 18-55mm lens won't do.
Autofocus systems are fast, but not usually instantaneous. You have to hold the shutter down halfway as you compose the first shot so the AF system can focus and lock, and then the camera fires instantaneously when you press the shutter the rest of the way. See Preventing Shutter Delay for more.

No autofocus


We tried the same lens on another Nikon (D90) and auto focus did not work.
We mounted a new set of lens on the original D40x, and it worked.
Turns out the 2 year Nikon lens (18mm-135mm) was bad. Nikon lens have a 5 year warrantee. The lens will be sent back to Nikon with no service or shipping charge.

Thanks,

Nikon d40 autofocus


Look on the left side of the lens. Make sure the button is on A for auto focus and not M for manual. OR not stuck in the middle. Hopefully that will solve the problem.

Nikon d40x shutter problem


May be a weak subject to focus or the flash is not ready when you press the button.

Set the camera to auto(green) mode.Try it with a contrast bright subject for as many time as possible.
If the problem persists turn off the camera and reset the camera using the button near usb connection.

Then go to seller for replacement.

Nikon D40X stopped auto-focusing yesterday


I had the same problem. My issue was with all my lenses. I solved it by going to the menu and selecting the custom setting menu (pencil icon). Then from the right menu select the AE-L/AF-L and press OK. Then make sure it is set on AE/AF Lock. Presto...all my lenses worked on auto-focus.
