fairly reasonable.
Even with the lcd turned off, I believe the LX3 and know that the GF1
and G1 still have the shutter open until the shutter release is
pressed fully. Then the shutter closes, the sensor gets flushed
(electronically reset) and then the shutter opens and closes for the
exposure.
Since this activity is consistent, it can be accounted for and after
a while it doesn't intrude much into the process.
With those cameras that don't move the lens until you fully press the
button, the lag is again variable and so can't be properly
anticipated.
