It wouldn't sound like a DSLR since it has no mirror... I guess thats the most obvious part
to me its sounds pretty darn subtle... DP review has the
soundbyte of the M7 verses the M8 ... you can hear the difference
Its slightly louder and has that little buzz to it... were talking cloth versus metal
If you want ... compare the sound above (the 2nd is the M8) to this clip of a D80 in
continuous shotting mode
... thats a D80 doing about 50 pictures at 3 FPS
