OM-D too small?

Srt101 is shorter, and FTB is the same thickness! As for width, E-M5 is not as long since it doesn't have to accomodate the roll of film, so it's only 2.4cm or almost 1inch less long than the LONGEST camera on this list...But as your left hand should be holding the lens anyway, you shouldn't notice that difference. Hardly noticeably smaller!
