I'm thinking this is covered somewhere but the search terms are all too short and rejected.
Basically I have a D300s and SD card. I have a spare CF slot. I don't have a CF card. Regardless the superior features of CF cards, I just want a backup. I looked online for CF to SD adapters so I could use a 2nd SD in the CF slot. I only found type 2 sized cards.
Is it possible to get something so I could use a 2nd SD in the D300s?
