Oops, I meant non-standard 4GB SD card.

Transcend makes a non-SDHC 4GB that works on non-SDHC compatible devices:

I will have to retest the 4GB Transcend on the camera if you're interested in that, I'm a bit fuzzy on my memory. I'm sure 1GB and 2GB cards worked fine though. The 2GB Transcend has a yellow label just like their non-SDHC 4GB card... so that threw me off.

For sure the adapter doesn't work with 4GB SDHC and 8GB SDHC cards that I have though (Kingston, Toshiba, A-Data).
