Sorry, but the Sony branded Memory Stick are outrageously expensive. There is a small but nice method the capacity of a camera, which has only a Memory Stick slot to increase: with this adapter: Memory Stick adapter for microSD cards. Even with a Sony V3 I could with this adapter increase the capacity to 16GB in a camera that will not recognize fast cards. I have already spent a lot of money for memory cards. (64MB for 300 DM in 2000 !!!) Since it is a satisfaction for me to get away from this overpriced tickets. Otherwise, I am very satisfied with the Sony cameras, since they allow for the SDHC cards.
