Cnaon power shot A70

You might have locked memory card. If not first try to connect memory card to PC with memory card reader and try to copy your stuff... then after you take all stuff try to format it.

Hi,
Its known problem of CCD Imager in your Canon A70 camera and Canon will repair it free of cost.
Click Canon CCD Imager Advisory for details.

Does you camera use CF cards?
If so the may work but some of the newer high tech CF cards are made for newer cameras.

It may be worth a shot to try the 2GB card and if it does not work, sell to someone who uses those.

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.
Please do rate and thanks for using FixYa and Best fo luck to get you camera out of E18!

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 if the camera is out of warranty they're worth a try:

Guest has a different problem. Guest's problem sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your cameras warranty status. Please check the following two links for more info:

mine just started doing the same thing a few weeks ago. I had downloaded pixes to the computer, went outside to take picture and it started acting up. strange lines appear on the screen, but the codes are all there, and you can view the pictures that are on the card. no, the card is not full, the batteries are fine. I think it has a virus built in to start trouble so we will go buy a new one!

i got my camera a couple of mounths, but i have not used it alot. When i turn it on, the start up screen wold come on but e18 would come up on the screen and nothing would happen after. i desperately need your help to fix my camera. thank you.

You may be able to store up to 110 images if you use the camera in its lowest resolution mode. In high resolution, you may get only 24 shots. We wish we could tell you precisely, but it depends on the exact size of the file created by a given camera, as well as the resolution that you select. Keep in mind that Secure Digital, CompactFlash, and SmartMedia memory cards are competing products and are not interchangeable. You'll find a few cameras that are compatible with more than one brand, but generally when you buy a digital camera today, you'll be making a commitment to work with one type of memory card. Use the attached chart to determine the average number of photos that Secure Digital memory cards can store (compatible with most HP digital cameras)
