Hi Faith.

Hmmmmm....  Most Vaios have two slots - one for SD and one for MS.  It looks like Sony have dispensed with the MemoryStick slot on the new Vaio Fit.  This is a bit odd as MemoryStick is a Sony format - perhaps they are bowing to commercial pressures as most people use SD Cards these days.

I think you can still use MemoryCard Duo Cards but you need a cheap  adapter like this: -

Alternatively, you can use an external USB Card Reader or you can change to using SD Cards in your NEX-5.

Hope you are OK - See you soon?
