I have a number of cameras that take a range of memory cards.
1. SD
2. CF
3. Memory stick pro
4. XD
I have a range of media including genuine versions of all these as well as adapters to use micro sd / sd cards. So far I have not experienced any problems but am curious if there are any known issued with using adapters instead of the real thing. I have not measured performance but have not noticed any slowing down of writes and haven't had any experience with data loss
