If you want the higher
than standard FPS without the vertical grip, do the following:
First, make the following custom
setting adjustments:
e5: Flash only
e6: Flash only
f4: Button press - Bracketing burst
f4: Button + dials - Bracketing mode
Set exposure manually.
Activate bracketing with the Fn + Command dial and set 9F (9 frames).
Set your shooting mode to single-shot (S). Do not use flash. Then hold
the Fn button and when you are ready to shoot, press the shutter
release and continue holding the Fn button. The camera will fire up to
9 frames at 8 fps.
To continue shooting
after 9 frames, you will need to let up on the shutter release and
depress it again. If you fire fewer than 9 shots, you will only be
able to shoot the remaining exposures in your 9-frame burst if you
continue shooting again, without letting up on the shutter release
again.
Since you have set auto
bracketing to apply only to flash, your non-flash bracketing burst is
fired at your manually set exposure — it is not bracketed.
