The Meike BG-E6 is a grip/battery pack designed specifically for the EOS 60D. This grip provides a solid and comfortable grip.
There are several reasons to purchase a battery grip for your camera. It often happens that a camera is just a bit too small for the size of the photographer's hands. European hands are slightly larger than the hands of the Japanese camera designers. In that case, a battery grip ensures that the camera is much easier to hold. Photographers who often take pictures in portrait mode also experience the pleasure of the extra shutter button that is attached to the grip.
Nowadays, digital SLR cameras are increasingly used for filming in high resolution. This is done in combination with the cameras' live view function. Because the battery runs out much faster, a battery grip is an ideal solution. After all, two batteries can be placed in it. Another advantage is the higher weight of the camera. In combination with large telephoto lenses, you can shoot with this extra weight much more stable.
