"restart" just means to turn off your camera and turn it on again. However, this rarely works for lens errors. Try these:

Fixing a Lens Error on a Digital Camera


This has to be THE most common failure mode for a digital camera. Some common error messages that might show up on the LCD's of cameras with this problem include "E18 lens error", or "lens error, restart camera". Some cameras might show nothing at all, but merely make a beeping noise as the lens goes out, then in, then the camera shuts off. Sometimes the lens won't even move.

The problem is actually quite common throughout all camera brands. 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. Believe it or not, one BIG contributor to lens errors is using a camera case. Sand, gunk, case fibers, etc... accumulate at the bottom of the case. These materials love to cling to the camera by electrostatic build-up from the camera rubbing against the side of the case (especially those cases with soft fibrous interiors). Once these materials work their way into the lens mechanism, that's all she wrote. I have many cameras, and NEVER use a case for this very reason.

A camera owner that suffers this problem may have no recourse for having the camera repaired. Many camera makers will not honor repairing this problem under warranty as they claim it is due to impact damage to the camera, or sand or debris getting into the lens gearing mechanism (neither of which is covered under warranty). The quoted repair cost is usually close to or more than what the camera is actually worth.

Fortunately, about half the cameras that suffer this failure can easily be fixed by one of the following methods. None of these methods involve opening the camera, although some have potential to cause other damage to the camera if excessively done. If the camera is still under warranty, before trying any of these, please please first contact your camera's maker to see if they'll cover the repair, or to determine how much they'll charge for the repair. Who knows, you might get lucky. But if they quote you a number that's higher than the value of your camera, you may want to consider the following methods.

The methods are listed in the order of risk of damaging your camera. Thus make sure you try them in the listed order. And remember, these fixes (especially #6 and 7) should only be considered for a camera that's out of warranty, who's cost of repair would be excessive, and would otherwise be considered for disposal if unrepaired:

Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on. If that didn't work, try pressing and holding the Function or OK button while turning the camera on.

Fix #2: Remove the batteries, then remove the memory card. Then install new batteries, and turn on the camera. If you get an Error E30, it means you don't have a memory card installed, so turn it off, slip in the memory card and turn it on one last time.

Fix #3: Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particles that may be jamming the lens. If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying fixes 4, 5, and 7 as a means to provide extra help to these fixes. But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera. Reinsert the cable only AFTER tapping the camera.

Fix #4: Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The idea is that the camera will try to autofocus while the lens is extending, hopefully seating the lens barrel guide pins in their slots.

Fix #5: Blow compressed air in the gaps around the lens barrels with the idea of blowing out any sand or grit that may be in there jamming the lens. Other variations include blowing with a hair dryer in "no heat" setting, or sucking the gaps with a vacuum (careful with this one).

Now we're entering into the realm of potentially damaging your camera in conducting the fix. There is definitely some risk here, so take care when conducting the following two fixes.

Fix #6: Repeatedly tap the padded/rubber usb cover on a hard surface with the intent of dislodging any particles that may be jamming the lens. Other variations include hitting a side of the camera against the palm of your hand. A lot of people have reported success with this method. HOWEVER, there is also some potential for damaging or dislodging internal components with this method, such as unseating ribbon cables, or cracking LCD screens.

Fix #7: Try forcing the lens. More people have reported success with this method than with any of the other methods. HOWEVER, there's obviously some potential for damaging your camera by using this method. Variations include gently pulling, rotating, and/or twisting the lens barrel while hitting the power button. Attempt to gently straighten or align the barrel if it's crooked or twisted. Another variation includes looking for uneven gaps around the lens barrel, and then pushing on the side of the lens barrel that has the largest gap (note pushing the lens barrel all the way in is NOT recommended as it may become stuck there). While doing any of the above, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera.

Lens is not retracting. Display shows lens error, restart camera. But the same appears after restarting


Your lens does sound like it needs to be replaced, but I would recommend dealing directly with Canon. If your camera is still in warranty they may do the repair for free, if not they will replace the lens for a flat rate charge of $159. It's a little expensive, but it will be done right, using a brand new lens.

Canon SD770 IS's lens won't close. I get error message: Lens error, restart camera. Restarting doesn't work. Any advice? Strange that it won't even take photos or playback while the lens is stuck!


Welcome to FixYa

Camera detected this error while moving the lens and cut the power automatically. This error message may appear if you press on the lens while its moving. Make sure that when your going to turn on the camera, your hand or fingers will not block the lens to retrack. Turning on the camera in a dusty or sandy environnment is also one reason for this message to be displayed.
Try to remove the battery and re-insert it, then turn on the camera again. If the message still persist, take the camera to a service center because there may be a problem with the lens.

Please let me know if you have any questions and if this solution was helpful.

Thank you for using FixYa

'Lens error please restart the camera' msg displaying


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.

I have a canon Powershot A480. It keeps coming up with the faultLens Error Restart camera. How do I do this


Service & Support Issue: Camera displays "Lens error, restart camera" on the LCD monitor.
Solution: Possible solutions for a Lens Error message PowerShot A480.

The "E18" or "Lens" error message indicates an error that involves the lens unit or lens cover.
This error may appear where the lens is prevented from properly extending or retracting such as, for example, when pressure is applied to the lens or the area surrounding the lens while handling the camera. The error may also be displayed if the lens unit/camera has been subjected to an external shock, or if a foreign substance (i.e. liquid, sand, dirt) enters the camera. Solution
Check the following when you operate the camera to avoid applying pressure to the lens and surrounding area:
  • Hold the camera so that your fingers do not touch the lens unit when you are shooting.
  • Make sure the camera is off before the camera is placed back in the case. Exercise caution to ensure that the camera does not accidentally power on while the camera is stored inside the case.
If you cannot clear the error code by turning the camera off and then on again, or if the error code is displayed frequently, a camera malfunction may have occurred. Please click here to set up service for your camera online.

Lens error, restart camera


Lens error is usually caused by mechanical faults concerning lens assembly. The lens cannot extend or retract fully, the error is detected and lens error is returned.
Sometimes this can be fixed playing with the lens during extraction or retraction to help the lens asset getting back to normal.
More often the camera lens must be disassembled and re-assembled by a technician to fix the problem.
