Btw time-lag, totally different problem:
Once every while, I find myself taking two shots in sequence, where
only one was intended, in Single Shot Mode, only because I didn't
lift my finger in one linear motion from the release button....
There ought to be a CF/SFC/PCF to prevent this by setting a minimum
time-lag between each shot, in Single Shot Mode only of course.
I also would like viewfinder info that tilts along with camera
position, so that numerical data & AF confirmation is always on the
bottom, exposure bar always on the right, regardless of portrait or
landscape mode....it really gets tiring to adjust your eyes each
time, especially if you are fighting to get the most steady position
of lens+camera, rotating it in every direction possible.
No Canon, you're not done yet with your analog cameras, not by far.
