❚❚ Cancelling Bracketing
To cancel bracketing, press the BKT button and rotate the main
command dial until the number of shots in the bracketing sequence is
zero (0F). The program last in effect will be restored the next time
bracketing is activated. Bracketing can also be cancelled by performing
a two-button reset ( 0 209), although in this case the bracketing
program will not be restored the next time bracketing is activated.
