Internal memory Can I take pictures without a CF? I forgot at home#$$%$##. I have heard that other cameras have this function? Can the CAnon Powershot A70 support? Thanks

There is no internal permanent memory. There is a buffer that holds data momentarily while the data is written to the memory card, but the buffer is flushed after each shot or series of shots. Sorry.

When you take pictures without the internal card , they get stored inside the camera internal memory (usually 8 or 16 MB only).

Connect the camera to a computer using a data cable, without putting any memory card inside the camera. The camera internal memory will be displayed as a new external usb disk on computer.

Highly recommend that you consider using a card reader to download you pictures. You insert the camera's memory card into the reader, and then insert the reader into a USB port on your computer. The card then shows up as a hard drive so that you can simply copy/paste or drag your picture files onto your computer. Card readers are much more faster in downloading pics, do not require the use of your camera's batteries, and provide much more reliable downloading of the pictures (fewer errors). They're also VERY inexpensive these days. Here are some examples of CF card readers from Amazon:

Also, if the card has somehow become corrupted, take no more pics until you've recovered the photos. Take the card out of the camera. Here's some freeware photo recovery software that should be what you're looking for:

You will also need to use a card reader with this software. Finally AFTER you've recovered your photos, recommend formatting the card IN YOUR CAMERA to prevent this from happening again. Note that formatting will totally erase your card. Turn on the camera, press the menu button, select the tools menu. Go down to the selection that states your CF card's memory capacity and select it. Then follow the formatting prompts.

The Canon PowerShot SD400 has no internal memory. All pictures are recorded on a memory card.

There is a service notice for this CCD issue and Canon is repairing this model for free. Give Canon tech support a call and they will send out a shipping label and within 2-3 weeks, you should have a working camera!

Hope this helps!

Check your memory card to see if its locked!

I just repaired my Canon G2 with the same symptom.  The internal PCB that you plug the external AC adapter is defective.  The numbers on the board are:

GCMK-M1X

Coolpix uses SD cards, not CF. Anyway, try using the camera without memory card, only with internal memory. If it works, then replace memory card.

It could be as well a malfunction CF card. Try to use another CF card in your camera. Good luck!

Well there is a known problem witht eh CF memory design, i hope this is not your problem but it may be. Take your camera into a well lit area or get a small flash light. Open the memory door and peek down inside the camera and look at the pins inside the camera. Are they all uniform? does any look bent or out of place? there should be 2 uniform rows no pins should be missing or out of place. If they are you have a connection problem. This is one of the issues with this memory format and its why they have changed the design to SD. This is common with people who remove the cards alot and use a reader over time the card and the slot becomes warn and its very easy to bend pins because the card isnt sliding in smooth. If this is your problem (a few bent pins) you may have to take it in for service or try and fix it yourself. Ive read about people using a mechanical pencil. Remove the lead and the pin slips right into the top and you can carefuly move it back. Hope this helps!
