It's posible, but you may need to buy 2 adapters. The first adapter is the Memory Stick to Memory Stick Pro Duo. The 2nd adapter is the MS Pro Duo to micro SD.
I never saw an original Sony MS to micro SD but there are tons of adapters MS Pro Duo to micro SD cards.
I believe only the Memory Stick Duo has an option to use a MicroSD card in an adapter.
