I use a D700, D300s and a D2x. I'd like to get a couple of CF cards that are larger than my current 8gb Sandisk Extreme cards that are compatible with all three bodies. Can I use 16gb cards with these bodies? If they work should I stay with Sandisk? I'm a raw shooter and on a day long photo adventure I fill my current cards quickly and that's the reason I'm looking into larger cards.
