But what about mechanical harm? Does the mechanism that controls shutter
speed allow intermediate settings without risking damage? The first quoted
post above suggests that the M6 is "designed so weak" that there is a
danger. My M6 doesn't seem weakly designed; I'd be curious to hear a more
concrete answer.
