Don’t have the MB-D10 grip for your D300 but still want a taste of what 8 fps is like?
Try this trick to fool your D300 into shooting at 8 fps!
First, make the following custom setting adjustments:
- E5: Flash only
- E6: Flash only
- F4: Button (Fn) press: Bracketing burst
- F4: Button (Fn) + dial: Bracketing mode
Then, do the following steps:
- Set your camera to 12-bit RAW mode or JPG.
- Activate bracketing with the Fn + Command dial and set 9F (9 frames).
- Set your shooting mode to single shot (S). And do not use flash.
- Press and hold the Fn button and when you are ready to shoot, press the shutter release while continue holding the Fn button.
- The camera will fire up to 9 frames at a blazing 8 fps! :-)

But then, rather than doing all those, you better just buy the vertical grip. It's waaay easier, and it's worth your bucks ;-)
