Hi jameswilby5,
Adding to what's already been mentioned:
- on some cameras you get a higher FPS (frame per second) performance
- many grips have controls, including shutter-release, LCD info screen and others, for when you you flip your camera in the vertical/portrait mode
- quite frankly, some use them to make their camera look bigger and badder/more professional in the eyes of people who do not know better..lol
of course, two batteries will last longer and, as popo also mentions, they can often take AA batteries, so in an emergency, you can use those if your other batteries have run out of power.
On cameras where battery life isn't too great to begin with and where you might use the built-in flash or really long exposures (both of which drain the battery noticeably faster) a lot, I can see it might make sense.
For example: both the Nikon D40 and D300 shoot in excess of 1.000 images on a charge, but the D200 is typically half that. Of course, you can just as well buy another battery and just replace it when the first one runs out.
Personally I haven't had any desire to get one - with my flash bracket, 2 flashes, umbrella and Tokina 11-16mm lens, my gear can be heavy enough as it is..lol...thank goodness for the Cameralabs strap!
Cheers
