Question about Canon PowerShot A720 IS Digital Camera

1 Answer

I have a Canon A720IS 8.0 meg camera that I'm having problems with. I have tried several SC cards; 1 gig and 8 gig. Same results. The pictures and video look fine on the LCD, but when I download to the Canon program, or any other program I have: Picasso, Microsoft, etc. I get the same weird results. Some pictures are okay, however, most are "redone". The result is that some of the picture is okay, but some is realigned. They are always straight lined corrections. The color will be lighter or darker in those "realigned" areas. The videos will start playing, and then the video stops but the sound continues okay. I noticed when I use flash it takes around 5 seconds for the light to go out meaning the picture is recorded. No flash, instant recording. New recharged batteries or not. No difference. This has been going on for about a year and now getting worse. Just came back from Christmas with triplet grandchildren...very dissapointing results.

    Guru,



    Thanks for the reply. I have used the cable with the camera, an external card reader, my PC internal card reader, my HP Photosmart All-In-One card reader: all with the same results; except different pictures are corrupt according to which source it goes through. Weird!!! I just used my internal card reader and d/l into Microsofts Windows Photo Gallery and they were all good. I have used Canons program that came with the camera; Zoom BrowserEX, Picasa3, Windows Media, HP Viewer, and Quicktime, and they d/l corrupt pictures. Not the same pictures and not the same corruption. Nothing is consistant. Weird!!

    I'm running Vista Ultimate, which scans daily and also use Avast.

    My main card I use was formatted in the camera and is an 8 gig SD card. I also tried a formatted 1 gig card with the same corrupt results. This one has me stumped!

This sounds like corrupted files. Are you downloading these pictures using your camera (ie through a USB cable attached to your camera)? If so, may I suggest using a USB card reader instead. If already using a card reader, suggest buying another one as it may have gone bad.

You plug the SD card into the card reader, and then plug the reader into the USB port of your computer. It essentially turns your SD card into a hard drive that you simply copy and paste or drag and drop the files from onto your computer's hard drive. It's very simple, no software involved.

Card readers are much faster in downloading files and are much less likely to incur file errors. For these reasons most (if not all) professional photographers use card readers instead of downloading directly from the camera. Card readers are also very inexpensive. Here's an example of a nice cheap one. Try it, see if it fixes your problem. If so, then consider getting a better one later:

    Have you scanned your computer recently for spyware? Spyware can cause hangups such as this. Also, have you ever formatted your memory card in your camera. This can also help reduce such occurrences. But keep in mind that this will also erase your card also. If you've never formatted, place the card in the camera, press menu, then select the tools menu. Scroll down to the selection showing the cpacity of your card and select it. Then follow the prompts for a "low-level" format.

I get "card error" with


Hi, The camera is rated to take cards up to 256mb so that rules out your 1GB card. Try confirming the 128meg card works in a different camera.

Does not work with 8mb memory card. Why not please? Canon A540. Problem occurs when change a 2mb card for a 8mb card. Have not tried anything to fix problem


The A540 is designed to work with SD cards. Your 8GB card (I assume you really mean gig, not meg) is actually an SDHC card (SDHC stands for Secure Digital High Capacity). While SDHC cards will fit into SD slots, they will not work in SD devices. You need to keep using SD cards, 2GB and smaller.

I have a Toshiba 8 GIG memory card. I used it


When you removed the card from the computer, did you remember to use the "safely remove hardware" procedure? Also, you should never wait until your card is full before downloading...you run the risk of the card becoming corrupted. Your options now...1. Get a separate card reader and see if you can download your pics with it.2. If not, take the card to a store like Walmart that has a Kodak Picture kiosk machine. Insert your card and you should be able to see all your pics. From there, you can make a cd of them. Then, format your card in your camera to return it to factory specs.

Card Error


try going to wolf camera or ritz camera they have a 512 meg chip for about 8 bucks put it in your camera and see if you can format it and take pictures. I have seen in the past that the 2 gig chips are frauds they are smaller chips formatted to a 2 gig compositor. They have been going around quite abit. if that does not work then the camera has a defective sd port and should be able to be replaced from where you got it. if they will not repair it then call casio you can find their number at www.casio.com/us then under contact us. Casio should fix it if you bought it from a retail store send them your receipt. That what they ask for to see when the warranty started. Hope this helps.

Do you mean you want to use a 1 gig xD card in your C-750? You can't do that. The C-750 has a memory card size limit of 512 mb.

New SD Card wont work - all the others I have do!!


I believe any SD cards larger than 2Gb are technically SDHC cards, which are not compatible with all cameras. Kingston is a decent company so I'm guessing it's not because the card is a dud. If your camera doesn't advertise SDHC compatibility then I don't think you can get the card to work in it.
