But isn't the variable "part" of the lag AFTER capturing the exposure?

I using a 56 on an X-Pro1, I have verified that the time required to complete a shot, when stepped down and in manual focus mode, does vary depending on the direction of the most recent focus adjustment.  It clearly takes longer to get control of the camera back when immediately prior focus change increased the focus distance (I have not tried it with the focus direction flipped).  You can even hear an "extra" sound at the end of the exposure process when your last focus adjustment increased the focus distance that is not present when the most recent adjustment decreased the focus distance.

However, as best I can tell, this happens after the shutter has open and then closed.  Which is to say, it shouldn't affect the actual lag in terms of getting the shot.  Of course, it does affect how much time it takes to get control of the camera again, and the screen blanks a little longer, so I absolutely agree that it is undesirable.  However, as best I can tell it does not affect the amount of time required between pressing the shutter button and capturing the image.

But I'm just doing a quick test.  Does your test data bore this out, one way or another?
