for cell cam i would think twice, normal every day camera should be fine.....few cell cams i've had were very picky about having a class 10 sd card in them, has something to do with transfer speed of picture to the card and then the upload to cell towers and having an adapter is likely making that process slower and could cause issues. It did for me at least, i popped not just any old sd card in but made sure it was class 10 and haven't had issue since.
