You may use any SD or SDHC cad. SD cards range up to 2GB in size, SDHC cards range from 4GB to 32GB.

You may use any SDHC card up to 32GB in size.

Hi

Sure you can as it supports SDHC cards too.

Yes, the SX20 IS will support SDHC cards up to 32GB in size.

The SD1100 can use SDHC cards up to 32GB in size. If you need more memory, you can use multiple cards simply by removing the card in the camera and inserting another one.

You can buy SDHC cards at any department, electronics, or office-supply store.

The ImageMate 5-in-1 is compatible with SD, MMC, MS, MSPro, and xD cards. It is NOT compatible with SDHC cards.

While SDHC cards will fit into SD slots, they will not work in SD devices.

Your camera, introduced in 2006, cannot use SDHC cards, but only 'standard' SD cards up to 2 GB.

You should always format the cards (if needed) in the camera and not in the computer to ensure compability.

Here's the specs for your camera from Canon. Sorry, but an SDHC card is not listed as compatible with your camera. Only SD or MMC. Now look on your 16 and 32GB cards. You'll see SDHC stamped there. Although SDHC looks exactly the same as a standard SD card, the format the cards use are very different. Unfortunately your camera was designed before the SDHC format came out.
You'll need to instead purchase a standard SD card (those that are 2GB or less). Fortunately these are very inexpensive these days, with 2GB cards going for around $6 with shipping.

The largest SD card you can use is 2GB, but that's only because SD cards only go up to 2GB. You can also use SDHC cards from 4GB to 32GB. You cannot use larger SDXC cards.

the a 620 only goes up to 2 gb no higher
