Your observation is perfectly in order. The long shutterspeeds of the Leica
M6 are controlled by a mechanical assembly that controls the start of the
travel of the second shutter curtain. The longer the speed set, the later
the second curtain closes. The sound you heard is the spinning of the
geartrain that controls the long speeds (you hear it at best at 1/15th second).
Another advantage of mechanical components: they sing and dance while with
electronics its the silence of a cimetary!
