The 1/3 stop variation that was tossed out earlier would equal a 26% variation from the nominal shutter speed. In the worst case from the above example the 1/2 sec. shutter speed was off by 15%, roughly a 1/6 stop error. Perhaps this is why you don't see a lot of posts on the LUG complaining that shutter speeds are off. Despite the apocryphal claims to the contrary, the M6 shutter speeds are sufficiently accurate. - -Charlie
