"Approved SD Cards - Coolpix 3200
Answer
Nikon has tested the following cards and approved their use in the Coolpix 3200:
SD memory cards:
SanDisk 16/32/64/128/256MB
Panasonic 16/32/64/128/256/512
Toshiba 16/32/64/128/256MB
Other brands and capacities of cards may work, but Nikon cannot guarantee their operation. Check with the manufacturer of the third-party card for compatibility information. Nikon recommends keeping one of the approved cards available for troubleshooting.
Multi Media cards (MMC) are not recommended and should not be used "
From their web site. Just asking, did you look?
