The E18 error is 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.

Here's some things that you can do to try to correct it. They only seem to work for about 50% of lens errors, but they're worth a try:

Message e18

There is some sand or other light material blocking the lens

Jan 19, 2010 | Canon PowerShot SD400 / IXUS 50 Digital...


Working with E18 and cannon cameras

he E18 seems to be a significant flaw in an otherwise great camera.

It is a flaw well know by users of Canon Powershot and Ixus cameras and is currently not acknowledged by Canon as a flaw in camera design.


Canon E18 error happens when the lens gets stuck while trying to extend. The camera will beep a few times and the LCD will display a little E18 in the lower-left corner. The lens gets stuck in the extended position, and refuses to move either to focus the lens or to retract when powered off.

Apparently, people who posted about this incident on forums say they had to send the camera for repair and that Canon has horrible customer support and response time.

The problem usually happens because dirt or sand get into the lens mechanism. But it seems that more and more people are showing, who took great care of their camera, and still started receiving E18 errors.

It seems that the problems have been happening with the following types of Canon cameras:

- Powershot A40
- Powershot A60
- Powershot A70
- Powershot A75
- Powershot A80
- Powershot A85
- Powershot A95
- Powershot A400

If your camera is still under warranty, the best thing you can do is to take it to the nearest official Canon repair shop and Canon should fix it for free.

If your camera is out of warranty, or if Canon refuses to repair it for free (happens sometimes if for example they suspect the camera has not been treated properly) you can try some of the methods listed here to repair it yourself. These simple methods have helped a lot of people fix their cameras.

Before trying any of the suggestions, make sure your Canon has fresh batteries and it is in recording mode.

1) Remove the batteries from the camera, wait for a couple of minutes, then put them back in and turn the camera on.

2) Try compressed air. With a fine tip blow off gun and dry compressed air (20 lbs) set the tip between the lens turret and the camera body and turn on the air while moving the tip around the lens. It should remove all dust and sand. Turn the camera on and it should function fine.

3) Another method is to tap the padded USB cover part on a hard surface, for example, a desk. It sounds so simple, but very often in works.

4) Try forcing the camera lens:

Turn off the camera. Place it on the back with the lens facing up and take a look at the spacing between the lens and the lens housing. If you notice that the gap is not even all the way around the lens, the problem should be easy to fix. This type of a problem usually occurs if the camera was dropped while the lens was extended.

Simply - VERY GENTLY - press down the lens on the side where the gap is the biggest. You should hear a "click" as it pops back into place. Try powering the camera back on.

If the lens doesn't extend at all or it extends, and then retracts again, do the following. Turn the camera off. Take the camera in one hand and with the other gently take one part of the lens and gently move it round in a circular movement. Do so with both sections of the lens. You will hear a "click" as it pops back in place. Power the camera on.

Another version of this fix would be to pull and twist on the largest ring of the lens while turning the camera on. Listen for a "click". If at first the focus seems to be off, turn the camera on and off and take lots of pictures, close ups and distance. Focus should slowly start improving.

5) If that doesn't work, there is an online guide for dismantling Canon cameras and fixing the E18 error. (NOTE: Try this only if your camera is no longer under warranty!) It is a great guide with pictures and it can be found here.

There are 2 other guides, one Bulgarian and one Estonian with the take apart procedure for Canon cameras. They are not in english but have a lot of pictures which help with the process.

E18 is the canon fault number for lens error. Is the lens stuck out? does it click when the camera is switched on? Try lightly tapping the lens on a hard surface. This sometimes resets the lens. If all this fails take it to bits! (but watch the flash module as this can give a nasty shock.Big black capacitor) You will see the lens module take the it to bits carefully and re seat the components. I have done a few over the years. It takes about an hour. If you have any more issues contact me.

E 18 problem

the E18 means the lens system has a problem. I had it with my S2 and sometimes it worked, sometimes not. Eventually it stopped working. The only solution was sending it to repair, they changed the lens system.
