Saying that photographers not liking shutter lag should know about anticipating the moment is one of the most ridiculous things I've heard lately... Hey Erwin, why don't we ask for a bit more shutter lag on all Leicas? There are thousands of situations where we anticipate the moment and we have already composed and all we're waiting for is something (a face, an order: geometry between elements...) that happens for less than a second and just goes away forever... I have never used an X100 and don't know if it has any degree of shutter lag, but I agree with thousands of photographers: shutter lag is something I hate as photographer, because the photograph is taken in a different moment than the one I chose: the taken photograph is another one.
Cheers,
Juan
