Hi:
I did a little research for you. Check these web sites out:
http://www.squidoo.com/moultrie-I45
This one claims to accept up to 4GB SD card.
http://www.moultriefeeders.com/produ...id=mfh-dgs-i45
This one claims to accept up to 16GB SD card.
http://www.chasingame.com/index.php?id=114
This one claims to accept up to 16GB SD card.
The last two websites give a good review with the better one on
Chasingame. A 16 GB SD card would be nice as it is getting harder to
purchase the old 2GB SD card due to new technology and a high demand
for the larger cards.
This sounds like a very nice camera. Hope this helps.
