8GB SDHC card - will it work in all cameras?

londonman81

I have been looking at 8GB SDHC cards on ebay. I am tempted by the large storage capacity of these cards but have noticed that they are called 'SDHC' and not just 'SD'.

Are these cards compatible in all cameras? Or only some? If so, which ones?

I have a Canon S3 IS.

just had a quick search and hope this helps


What is SDHC?
SD High Capacity (SDHCTM) card is the new SD™ memory card based on the SDA 2.00 specification, introduced by the SD Card Association. This new SDA 2.00 specification enables SD cards to reach higher capacities - 4GB-32GB*.
Because SDHC works differently then standard SD cards, this new format is not backwards compatible with legacy SD format host devices.
More SDHC compatible devices are expected to be available in the second half of 2006.


To ensure compatibility, look for the SDHC logo on cards and host devices (cameras,camcorders, etc.)


Compatibility with SDHC 4GB:
4GB SDHC cards can only work with SDHC compatible host
devices. To ensure compatibility, look for the SDHC logo on
the packaging. Please check with your device manufacturer
for their current/future supported SDHC devices.

What is Class Speed Rating?

The SD Association has created and defined 3 speed
classes to help you identify speed and performance
capabilities/minimum requirements of SD/SDHC cards
and the host products. The SD Speed Class Ratings
specify a minimum sustained write speed for SDHC
cards (Class 2: 2 MB/s; Class 4: 4 MB/s; Class 6: 6MB/s*).

You can look for the Speed Class Logo to identify the
performance class of your memory cards and host
devices.

NOTE: SDHC, the SDHC logo and SD are trademarks.
*1 megabyte (MB) = 1 million bytes; 1 gigabyte (GB) = 1 billion bytes.

First of all, a quick look shows that Canon say NO, SDHC will not work in the S3.
However (disclaimer : please do not do anything based on this - please google first), some people have reported success using 4GB SDHC cards, I cant find anything about the 8GB cards.

The which ones question, it's very hard to answer - your best bet is to look up the camera you want, then check the media afterward - I dont know of any list that allows you to check by memory type - but i'm happy to be proved wrong

The problem with SDHC is that it is physically identical to SD, except the memory addressing is different. more info at (http://en.wikipedia.org/wiki/Secure_Digital_card#SD_and_SDHC_-_compatibility)
