Tell you what, Mr_Fusion. You call Canon at 1-800-OK CANON and ask them whether it is OK to use micro cards with adapters in their Cameras.

If they say it is OK , I will always answer the question with "I don't think it is a good idea, but Canon and Mr_Fusion must know more than me, because they say it is OK."

The one thing you do not want to do is be changing your card. Even though it is quite often offered as an option for people, the most common cause of SD card failure is mechanical. Usually the connectors will fail after repeated insertions and removals when there is a failure.

Sorry I can't help more than that.

The most common cause of failure is mechanical, I agree.  That’s the best argument against using micro-SD cards.  But, do not reply to observation.  Please.

Your claim that Canon does not say you cannot use micro-SD cards, is too hard to argue against.

All I can say is that in the 3+ years that I've been following this forum, we've fielded enough complaints that turned out to be solved by stopping the use of micro-SD cards to convince many of us that it isn't a smart idea. And if you believe that the contacts are a memory card's weak spot, why use a setup that has two sets of contacts instead of one?
