The response is disappointing, but at least it’s an honest answer:
At this time we have not tested any 16GB cards but may do so in the future. Watch this page for updates:
Title: Approved CF Cards - D200
Sorry we can't help more—David
Of course, it’s not true that Nikon “can’t help more”—Nikon can proactively buy a 12GB and 16GB SanDisk card and test them! For that matter, I’m skeptical that Nikon can’t get a free or loaner card from SanDisk! In fact, I’d be surprised if Nikon doesn’t already work closely with SanDisk (and Lexar) to ensure card compatibility with their DSLR cameras.
Most likely Nikon engineers are already preparing a firmware update to solve the problem, but as usual Technical Support will learn of it only once the firmware update is already posted.
