E18 Error Fixed! (Canon PowerShot SD450)

Huzzah! I finally fixed the E18 error I’ve been experiencing on my Canon PowerShot SD450, which prevented my lens from extending when the power was turned on, and the fix wasn’t nearly as difficult as I had expected. I’ve even snapped some shots of the process so that you can follow along at home, and fix your own camera if you are experiencing the same problem that I was.

Canon_Ixus_II_with_E18_errorIf you’re not yet familiar with the E18 error, check out this information on the topic from Wikipedia:

The E18 error is an error message on Canon digital cameras. The E18 error occurs when anything prevents the zoom lens from properly extending or retracting.[1] The error has become notorious in the Canon user community as it can completely disable the camera, requiring expensive repairs.


This is a fairly prevalent problem with the PowerShot cameras, and a class action lawsuit was filed (but dismissed) against Canon:

A Chicago law firm, Horwitz, Horwitz & Associates, has already filed a class action,[4] while the law firm of Girard Gibbs & De Bartolomeo LLP are investigating this camera flaw and may issue a class-action lawsuit against Canon.[5] There is at least one other.[6] Although the suit was dismissed in a court of law, the plaintiffs are appealing.

Fortunately, at least in my case, the fix did not require returning the camera to a Canon repair facility or having to take unreasonably complex steps.

My solution for the PowerShot SD450/IXUS 55 follows:
(You’ll need a very small Philips head screwdriver, #00, to remove the screws)

  1. There are six screws holding the metal frame of the camera body together, two on each side, and two on the bottom. Remove all screws, pop the strap-hook plate (sorry, probably not the most technical term there), then gently lift the front plate off by pulling up from the bottom, and remove the back plate in the same fashion. These should come off relatively easily. This is what the camera should look like as you remove the plates:
  2. Now, looking from the top of the camera, you should see a small motor on the left side, as shown below (it’s beneath the cable with a “22” written on it):
  3. Take your screwdriver (or another small instrument) and gently try to rotate the plastic piece attached to the motor on the left side, as shown below:
  4. At this point, try placing the battery back in the camera (if you have removed it), turn the camera to one of the capture modes, and press the power button. If all went well, your lens should now be able to extend and retract properly.

Further information (and other repair tutorials) are available at the following locations:

Unforunately, the site that had the most comprehensive information about this issue, e18error.com, seems to be down for the time being. Here’s a quote from their site that I saved in another blog post before the site was taken down:

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.

Here is how the E18 error looks like. You just get a black screen with small “E18″ sign in the lower-left corner:

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.


Please share your experiences with this fix, or the E18 error in general, in the comments below. Thanks for reading!

dPS: How To Remove Dust Spots From Multiple Photos in 4 Steps

Another excellent article from digital Photography School, about how to remove dust spots from your photos. I’m going to need to try this out on my own photos, especially after that full day of shooting with a dirty sensor (see the before/after examples here: https://blog.wolffmyren.com/2008/07/07/before-cleaning/ and here: https://blog.wolffmyren.com/2008/07/07/after-cleaning/)


Dust. The eternal enemy of a digital camera. When you shoot pictures with a digital SLR camera long enough, you will come to know the pain that dust can cause. For some it’s a minor annoyance. For others, it costs time and money attempting to salvage vital images.

In this post Peter Carey shares some tips on how to remove dust spots from multiple photos.

With advancements in DLSRs has also come advancements in Photoshop tools to remove dust. My favorite for dust removal, partially because of its price, is Photoshop Lightroom. While it is a scaled down version of the full blown Photoshop, it is perfectly suited to remove 90% of the dust I encounter.

Why is dust such a problem? Take a look at the picture on the left. Do you notice the small black spots in the sky and one big spot on the left side in the mountain? Those are not UFOs and that is not a mining tunnel. It was dust adhered to the sensor, casting a black shadow on the sensor when the shutter was activated. You can’t get back the data that is covered over by the shadow, but you can get creative and repair the damage depending on the dust location. When those dust spots are in the same location on each image, you’re in luck as there is a fairly easy method for multiple photo dust spot removal. (Note: the instructions are given using a PC version of Lightroom 1.4. Mac instructions vary only slightly if using a single button mouse)
