I'm prepared to buy a 8G "Memory Stick Duo". There is no memory stick for backup on the captioned camera, only a 4G built-in memory.
On computer shop I found "Sandisk Memory Stick Pro Duo" 4G and 8G. Does "Sandisk Memory Stick Pro Duo" work on the captioned camera without problem. Any other brand names I can look for? Comment shall be appreciated. TIA
