Hey everyone, I just upgraded from a Nikon D7000 (kit lens and 35mm 1.8) to a 5D Mark III and 70-200 IS II and boy am I loving it! I do have one question/concern though: the battery seems to drain rather quickly (at least compared to my D7K.) I've taken ~150 shots and maybe have spent 30 minutes in the menus and the battery is at 39%. No live view. Does this sound quite normal?
Thanks in advance
