Agree with you KV. The issue is that by using a micro-SD card and an adapter, one is introducing another mechanical interface into the chain of data transfer. It is not the same as just replacing a card (with another like it) it is a case of using the correct form of card for the interface. I say this not just from being an experienced photographer, but an engineer.
