I just bought my first DSLR and after charging the battery a little, inserting a Micro SDHC in an adapter, and attaching the lens I found myself stuck. The first message that appeared, in German, worryingly enough, was "Keine Speicherkarte" which I believe means memory card error. I tried it with another card and still the same issue. None of the buttons work and I can't access the menu. Have I been sold a dud or am I missing something simple?
