As I said earlier, if you can display or print without ressing-up the 
image then you didn't need the resolution that you sacrificed to f/16 by 
not shooting at f/11.  If you shoot at f/16 you've still got a 7MP 
image.  Better than an E1 and almost as good as any digital camera up 
until the last couple of years.  Furthermore, to make it painfully 
evident that you'd lost the resolution you'd probably have to shoot one 
of AG's USAF line charts.  :-)
