The new Nikon D5 is available in 2 different versions: one with dual CompactFlash memory card slots, and one with dual XQD slots. Both cameras cost $6,497 right now, and you’ll need to make a decision on which one you want when you purchase.
But there’s some good news: the decision isn’t permanent. If you decide you’d like to use the other format later on, Nikon will take your camera and exchange the memory card slots for you.
Nikon Rumors points out that on page 15 of the camera’s brochure Nikon offers to do this card slot swap at an authorized service center:
A fee does apply, though. No word yet on exactly how much the format swap costs.
