The following blog outlines some repair options for a lens error. They won't work for all cases, but they're worth a try if the camera's no longer under warranty:

When i turn on the camera the lense gos out then back in half way and the camera light flasshes and then it shuts off and beeps twice at me i have replace the battery with a new one and it does the same...

The lense has jammed and/or failed.
Could be jammed and you may be able to blow out some of the dust with an air can.
But chances are you need a new lense assembly. They can be found for as little as $30, but replacement is a rather complex procedure - with many pitfalls. But if you're venturous and willing to gamble $30+, it could make an excellent learning opportunity.
The lowest repair-shop quote I ever found was $75 in labor alone.
Guess I'm in the wrong business. ;-)

If you're wondering; yes, I was able to repair mine. Essentially it's a matter of taking it apart untill you have the lense out; remembering where it all went; and putting it back together -- In some extremely tight quarters...

Let's hope the air can works!

Good luck!

Have a brand new EOS 100D with Canon image

Have you actually cleaned the contacts or are you just looking at them and they "look" clean? Clean them with a cotton swab lightly dampened in rubbing alcohol.

I would check to see if the lenses work on another Nikon digital camera.Double check the A/M mode switch on both. Does it feels solid or mushy when you flip it back and forth?

I will say that both lenses use the same auto-focus gear assembly which can fail over time. Nikon only sells the assembly as a unit, so even if one of the small gears is broken or damaged, the whole thing gets replaced. You cab send them to Nikon or a trip your local camera store may be in order.

Lense will not go in and out... message at start up is "lens error, restart camera"

The lens of your camera has been stuck.
You need to go to Canon authorised service center. They will replace the optical assembly.


You can give it to an expert for repair, he can repair it without replacing the optical assembly.

Lens keep extended in an out

Hi. I had exactly the same problem with my Sony Cyber-Shot DSC-W7. The problem started after while lense was fully open, the battery became 100% empty. I did not have access to new batteries and did not have my charger with me so I put the camera on my car seat and went home. After charging the batteries, I turned the camera Off and the lense retracted 100%. Later on I tried to transfer some pictures to my PC. After connecting the camera to my PC with the dial in the P position and lense fully open I turned the dial to play in order to transfer photos. After transferring the pictures, I turned the camera off and disconnected from the computer.

I turn the camera on to take new pictures next day, The lense would go up, and and turn with lense fully open. It would never close. The screen was black with a message "Turn the camera on and off again". I tried 30 times or more and the same thing would happen again.

Here is what I did to fix my camera and it has been working normally since then.

1- I cleaned around the outside of the lense with lent free cloth

2- I used dust OFF to get raid of the remaining small dust particles from around the lense.

3- While turning the camera off, I pushed (down, up and turn) the lense in (NOT TOO Hard) by my hand. If you push the lense too hard, you may damage the mechanicall moving parts of the lense.

4- After a few tries, the lense retracted 90% +. I then pushed the lense a little harder all the way in, the way it normall retracts. The lense cover also closed 100%.

5- I turned the Camera on and off a few times. It was opening and closing exactly the way it used to. My Cybershot has been working okay since then.

I read a lot and here is what cause my lense to malfunction.

While lense was fully open and battery died, some small particles got on the lense and prevented lense from fully opening or closing.

In summery: two things could have caused your camera lense to malfunction.

1- if you had dropped your camera hard, some mechanical parts may have got damaged or dislocated. In this case you have to open the lense and replace the damaged part, clean and put it back on the camera. This is too risky for most ordinary people. You would most likely make it WORST.

2- If you did not drop it, most likly, some how some small dust particles got on the outside of the lense and they prevent the lense or the lense cover from fully opening and closing. If this is your case, please follow exactly what I did and your camera would be back to normal.

GOOD LUCK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Error message in D 90 camera

I had the same problem (same kit). I even exchanged the kit for a new one, and had the same issue. I'm convinced it's the connection between the camera and the lense - when I wiggled the lense, it would sometimes return to normal. I considered cleaning the contact points, but then the problem went away. I've been shooting hundreds of times, without it happening once.

You most likely need the shutter replaced. I see them frequently. Not something you want to try yourself, as it is an in depth repair.
