Re: When I try to zoom, screen goes black and "E18"...
I won't say this is a solution but to prevent the lens retraction E18 message which seems to be common with Canon zoom lenses, I put the extension tube on mine. Sometimes I put a polarizer lens on it but usually I just leave it on to protect the lens when it is on. I have dropped it (on the carpeting at home) and never had a problem. If you have a Canon with a zoom lens, get a lens hood for it ASAP!! My wife's A520 has one on hers too. No problems.
There are lots of other places on the web with suggested fixes. Keep looking and keep enjoying this camera. Merry Christmas all.

Canon E18 error happens with lens issues. Usually happens when lens gets jammed or dirt or sand finds its way into the lens. Sometimes it happens for no reason. You can try to gently tap your camera on the side and see if that helps, but if it does it will probably reoccur again at some point. Most likely you will need a lens replacement.
"E18" indicates an error that involves the lens unit or lens cover in your camera .This error appears where the lens is prevented from properly extending or retracting .The error may also be displayed if the lens camera has been subjected to an external shock, or if a foreign substance (i.e. liquid, sand, dirt) enters the camera.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 and might require service from canon.Or else try pressing the power button on and held it down while extending the zoom lens. The lens will extend out and the camera will be freed from the error.
Your problem in your lens...Try to bring service center. Cause, canon lens it for me it not easy to disassembe dan assemble it again...Different with other camera lens, like KODAK and Samsung. At sony camera "E18" can be "Turn the power off and On again" like my Sony W.35
Canon Powershot's error E18 has to do with the lens:
If it appears on a black LCD with E18 written on the corner, it is mostly due to the lens getting 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. I am giving below a link which will help you with E18 problem.
Hope this helps, let me know if you have a proble.

The following blog outlines some simple repair options for a lens error. But please first try the listed Fix #2. I heard that fix particularly works well for a camera who's battery had run down with the lens open. Please post back here with a follow up comment if any of the fixes work:
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. Have already fixed two A400 cameras with this problem by using these methods:
The E18 error message relates to a problem with the zooming mechanism (lens would not retract or extended)
Press the power button on and hold it down while extending and twisting the telescopic zoom lens. It might fix you problem.
In any case it could not make it worse
