Hello

The problem is that the lens has become stuck in the barrel after dropping it. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful.

Regards
Andrea

I have a sony cyber t70 camera and have an error code E:61:00 come up on screen and i cannot take a pictue please help me .. what solution can i find for this.. venkatesh


Sony claims that the E:61:00 error means "Difficult to adjust focus Inspect the lens block focus reset sensor". In my experience this means that the gears that extend and retract the lens are somehow jammed. This could easily happen if you hit something with the camera with your lens in extended (working) position.
You should try to:
- power off the camera
- place your thumb on the back of the camera and the fingers a few centimeters from the closed lens
- power on the camera, and with your fingers stop the movement of the lens forcing not to fully extend
- when the lens retracts or stops and then continues to extend, let it go

sometimes this would resolve the issue.
You may want to check this site:

wich has similar trick for a different model from sony, but the error is the same.
Be careful not to force the lens too hard or you may worsen the issue.
Let me know if this helped, good luck

Lens error appears on my ge e850 camera lcd screen


Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ... Unfortunately, many cameras that fall prey to this can only be corrected by professional repair. But, here are some things that you can do that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty, they're worth a try.

Lens Error - Restart Camera : Lens remains in extended position.


I had the same problem with the same camera. Ended up twisting the lens by hand back and forth while powering the camera on and off till the lens pins finally realined and let it close properly. Took alot of patience and care but has worked since. Usual cause of this problem is powering camera while the lens is blocked from extending, ie in a case, laying on its face etc.

Casio Exilim Z40 - Lens Error Message


You can try to "fix" this problem by holding down the shutter release button as soon as the camera power up.If this does not work you will need to replace the lens assembly. This should only be done by a qualified tech.
This is usually caused by one of two circumstances. (1) The user dropped the camera while the lens was extended causing a mechanical failure. (2) The lens attempts to extend while in a pouch or pocket without the user's knowledge. This usually happens when the user is carrying the camera with the battery in. When/if the REC button or power button is pressed accidentally, the lens will attempt to extend but can't. This causes the servo motors to "smoke".

Canon SC100 Lens Error


I have a 3 year old Canon PowerShot SX100 IS. While testing an external battery power supply I built, the external power connector pulled out while the lens barrel was extending just after I turned on the camera. Power to the camera was lost before the lens barrel fully extended and wouldn't reset when I repowered the camera. The dreaded error message "Lens error, restart camera" appeared and the camera shut down. I restarted the camera over and over and over again but the lens wouldn't reset. I was extremely lucky to find the information here and read various fixes. I didn't want to take the camera apart so I tried various fixes others have successfully used. I first tried smacking the bottom of the camera hard with the palm of my hand just after pushing the on/off button but that didn't work. The one which worked was smacking the camera on the side immediately after I pushed the on/off button. I smacked it quite hard twice with the palm of my hand then, suddenly, the lens barrel began to move and the lens reset itself back to its starting position. Thanks to everyone who has posted here!

Canon A720is turns on, but lens will not extend


I had the exact same problem. Since my camera is out of warranty, I decided to try to fix it myself; figuring the cost of repairing it would be close to the cost of a new, better camera. If yours is still under warranty, let Canon fix it for the cost of shipping.

I unscrewed all of the screws and carefully pried open the back of the camera. Part of it will come apart easily, but for the part that wouldn't, I slid a razorblade into the crack between the pieces and used it to separate the pieces.

I was shocked by what I found. The "mechanism" for switching between picture and review mode, appears to consist of a tiny black piece of something (doesn't look like metal, but I assume it's conductive). The physical switch that you operate on the back of the camera, appears to push this away from the circuit board. When that happens, the camera goes into review mode.

I assume that over time, this flimsy piece of whatever begins to wear out and eventually won't return to the circuit board. I slipped a small screwdriver under this piece and bent it back towards the circuit board.

That did the trick, The camera now functions as it's supposed to with one exception. Now, when I go into review mode, the lens won't retract (although it will when I power the camera down). Personally, I'm fine with that, because the lens going in and out is a huge waste of battery.

One thing I learned from this is that when you leave your camera inactive for long periods of time, make sure it's in picture mode, as this should reduce the strain on the flexible "switch".

I have an Olympus SP 320 camera, zoom error comes up and it shuts off


I just pulled my 320 out after not using it for 4 months and the lens extended and zoom error began flashing on the screen. After reading a few other post on the net about how much it cost I decided the camera was a goner. For good measure I banged it on my mouse pad a couple times and the lens suddenly retracted and it is now working fine. Doubt it will work very often but might be worth a try. Make sure you hit it on something soft to prevent other damage.
