Sony has finally admitted that it's MemoryStick card format might not be the best for digital camera users with the launch of an SD card range at CES in Las Vegas.

Although Sony says that “the new cards will complement Sony’s existing Memory Stick line", it also makes the admission that it needs to "satisfy the needs of a broader range of users", ie everyone that doesn't use MemoryStick.

The new SD/SDHC and microSD/microSDHC memory cards, which – except for the microSD 2GB card - are all class-4-speed for high-definition recording, will come in a range of sizes from 2GB to 32GB sizes and speeds geared towards both professional and consumer photographers.

Not fully signing up to the idea of SD cards though Sony state that "Memory Stick is the recommended media for Sony products, offering a range of unique benefits".
