Lense problem I have a problem with my camera lense . The lense came out and would not go in back, i changed the battery and i still have the same problem due to this also i am not able to access no other feature on the camera.

1) Incorrect battery, use genuine battery. 2) My Canon 400D had a similar problem. Checks showed that I had a damaged standard 18mm to 55mm lense unit, and also gave me "change battery" error message. I had a similar problem with a 70-300m lens. The camera main lense needed repairs, the Tacumar lense was not worth repairing. Have a camera specialist check your camera and more specific the main lense unit.

No. This lens lacks an autofocus motor, relying on the camera to have one. The D5100 lacks an autofocus motor, relying on the lens to have one. Adding a battery grip does not change this situation.

The D5100 only autofocuses with lenses having an internal autofocus motor. Nikon designates such lenses AF-S, Sigma calls it HSM. Lenses without the motor will only autofocus with the larger and heavier Nikon cameras such as the D7000.

Hi there please follow the steps and let me know the result.
1. Ensure batteries are fully charged & clean the battery connector point in side the battery compartment.
2. Look carefully between the lens and the camera body for any sand, dirt or any damaged etc.
3. Try turning the camera with the lens facing down and shake to dislodge anything stuck
4. Try removing batteries and memory card, wait 5 minutes and refit the battery only.
5. Now turn on camera( with out card ) and see ,if working then fix the memory card & again turn on the camera. If working then fine . Otherwise format the memory card and fix back in camera again & try. Make sure before format the memory card take a back up all photos in your computer then format. If no luck then reset or restore the camera setting by pressing Menu key for 2 sec .. in not done the press both Menu & self time key for 2 - 4 sec.
i hope it will gives you success

Hi,please don't try to force the lens back in,just keep the camera in a safe dry box free from dust, till you change the battery of your camera,afterwards you can close the lens of your camera.

Take care

Check the MODE. With ANY camera with manual mode you can take black (underexposed) photos all day. If photos are black try and use an AUTO mode. Typical it has a GREEN Camera symbol. So many things can be set wrong on the camera and they are beyond this answer.

have you tries changing the battery in the camera. if you try to take a photo with a dead battery it will lock the mirror up. If changing the battery doesn't make the mirror release turn the shutter speed dial to "B" and that should release the mirror

Did you drop your camera? If yes you either damaged the lense mechanical parts. If some dust or small particle are on the side of the lense, it may prevent the lense from opening up. If the lense opens up and down a little bite try to pull it out by have very softely. If it opened fully, clean up the outside of the lense and turn your camera a few times. If it does not have a mechanical problem, it should be back to normal. If above did not help, the lense has to be taken out and inspect for broken or damaged parts and clean it and put it back on the camera.

Good Luck!!!!

Try different batteries. I got the same problem with my cyber-shot. The battery was too low while lense was fully open. I recharged, but the lense would not close. When I turn it on, It would say turn off and on again. I did that for at least 20 times. I finally put another set of batteries and while I turned off the camera, I pressed the lense in very softly. After a couple of times the lense retracted fully. The camera has been working normally ever since.

It is also possible some dirt some how got on the sides of your lense. Try cleaning the sides of the lense.

If you had no luck so far, then your lense may have some mechanical problem. The lense need to be opened and cleaned and put back together.
good luck

Defective Lens Block
