Hi Utuado I dont't know if this will help, but here is somethings that could contribute to the problem you are having. The light sensor should be faulty or dirty. But a dirty light sensor should give you lighter pictures as the camera should compensate. The settings could be changes so you have a higher Exposure value (EV) resulting in darker photoes There could be dirt or sediment on the camera sensor, blocking the light from being detected. You could follow the guide for repairing the autofokus, Repairing Nikon D3100 Autofocus as you also here has to clean the sensor. I hope some of these issues could be the cause of our problem :)

Hi gomezstevevincent :)

I do not own a D3200, but it is an upgrade of the same model. Therefore i think it will work just the same.

If you try it out and it works could you comment i here so others have the answer?

I wish you luck with your repair :)

Hi Lei Kim

As seen above there is some things that you can do to try and fix your lens. You can try de-mounting and reattaching the lense to your camera. This will test if the connection from the camera to the lens is functional, also to can try to clean the connection to improve the connection. If this still does not work you can try making the focus point a single point and moving it around in your viewfinder if the focus works with one or some of the points you can try to make this guide.

Hope it works

Hi Justin

Sorry to hear about your camera. This problem was that the auto-focus did not work due to dust or other impurities on the CCD sensor. I am not sure if it is the same problem. The D3100 does not have that many autofocus points and when i found the problem i could get it to focus if i selected some specific points. Your D800 has a lot more focus points so i assume that there should be a lot more dirt on the sensor for the focus to stop working. But it worth a try. Remember to check all other settings ;-)

Hi BrittneyMikula

Sorry to hear that you got problems with your camera, I did not hear about this problem before, but the problem may lie in a protective feature of the camera. So my suggestion is that you try to pull out the battery. wait a minute and reinstall it. Then try turning the camera on and off a couple of times, see if it can take pictures, also in manual focus mode. Then lastly turn the camera of again and try removing the lens.

An other problem could be that something mechanical is stuck in the opening function, here you could try to gently jittle the lens in its socket and see if the lens will come off.

Last advice of cause is to take it to an authorized repair shop.

If you find a solution please make feedback

Best regards

Hi Eventer

Sorry to hear that you have a problem. There are a few things that you can try to locate the problem. First of all you have to be sure that you have your auto focus setting set to AF(auto focus) and not MF (Manual focus). Next try if you can change the focus manually on your lense.

After this you can look at the connection between camera and lense, just as decribed above from April 6. 2017.

If there is still a problem you try to borrow or if you have another lense you can try this. If this work you eliminated your camera house as a problem, and have to find the problem with your lense.

hope this helps :)

Hi Jackie

I seems like it is the lens that is the problem. Since you got the standard lense to work. One other thing that you can do is take a look at the connection. This i also a problem I have experienced. There are the metal dots on the lens connection and corresponding connectors on the camera house. Make sure these are clean and free of any dirt or grease. A bad connection can create problems with the autofocus.

If this does not work you can also try to rotate the lens slightly back and forth to see if the connectors is a bit misaligned.

Hope this helps you :)

Hi you :)

The sounds indicate that the autofocus motor is the problem. You can test this by changing the objective and see if the sound disappears you located the problem.

Hi Kolby

Sorry to hear that you focus does not work. But as far as i know that focus is integrated in the objective. So if you can not even focus manually you should look for the problem here. Perhaps try to change the objective to be sure that the problem is located here on the objective?

The focus is a mechanical part of the objective that changes the focal point of the lens, if you can turn the focus without any change you should narrow your search to this area :)

Hope this helped you a little, and if you find that it is the objective that is broken you can always order a new one. Then you also have the change to upgrade or change the specifications. When i broke my Kit lens i got the Tamron 18-200 mm F3.5-6.3 Di II VC objektiv, to get a bit more zoom and playing room :)

Best regards
