3 File Numbering Methods
When the CF card is replaced with  a newly-formatted CF card, the 
folder numbering and file numbering will restart from the beginning 
( 100-0001 ). It will start from folder number  100 and file number  0001. 
This is convenient when you want to  organize images according to CF 
cards. If the replacement CF card contains images recorded previously, 
the file numbering will follow the highest file number (in the highest 
numbered folder) in that CF card. 
This creates a new...

76 About Predictive AF
If the subject approaches or retreats from the camera at a constant rate, 
the camera tracks the subject  and predicts the focusing distance 
immediately before the picture is taken. This is for obtaining correct 
focus at the moment of exposure.
  When the AF point selection is autom atic, the camera first uses the 
center AF point to focus. During autofocusing, if the subject moves 
away from the center AF point, fo cus tracking continues as long as...
