A grip typically attaches to your camera body through your cameras battery compartment and uses a cassette to store extra batteries Typical battery grips also have an additional cassette letting the photographer to use multiple instances of AA batteries.
If you do photography for a living, a battery grip may be useful to you. if you're a wannabe professional, or you just want to be 'noticed' by other people as being a professional photographer, a battery grip might be that all important status symbol, but who are you relly kidding?.
The design and layout of a battery grip is a through-back to the olden days of film camera motor drives. it might have been essential at one time, however this is no longer the case.
Battery grips typically fit just one or only a few particular camera editions, because they must conform to the body shape of the camera , power requirements, connectors.
A power grip's primary purpose is to add to the battery capacity. while a secondary purpose is to add some controls to the grip allowing you to have similar controls available when you turn the camera to a 90 degree angle.
Another use allows you improve upon the camera ergonomics by providing more space to hold on to your camera. Some grips let you use standard AA batteries allowing you to continue to shoot images as your camera's batteries are used up.
if you preview photos in your LCD display often then that could be some rationale to add to capacity of your batteries, but otherwise it's just not necessary.
If you are not near a battery charging location it can be great to have a substitute battery power source. Battery grips let an SLR or DSLR cameras to hold extra batteries to stretch the camera's standard battery life, plus provides a vertical grip plus an additional shutter release (and perhaps other controls), assisting in the capturing of portrait photographs.
Today's DSLR batteries are typically good for 300 to 600 photos and extra batteries are inexpensive and weight very little, why pack extra bulk and weight around.
