#13. "RE: Why Get a Battery Pack? MBD11"
In response to In response to 7


St Petersburg, RU
          

For a 18-105 that is light compared to the camera, so the mid mass point would naturally be close to the base of the grip. Support by the bottom of the grip might be fine for such light and short lenses but as soon as you add length and mass the moment arm makes that approach less stable, I think you will find that moving your hand out to a balance point will solve the instability problem a heavier lens induces.
Any movement by your hand will define an arc that the front of the lens and the focal plane swings through. A longer arm, meaning a longer lens, means the slight movement at the camera support point will be multiplied by the arm length so a tiny movement by your left hand at the base of the grip will result in a front lens switch of a much greater distance. The least arc swing at the lens front and focal plane will be when the arm is shortest, which is in the center of the mass, between the from element and focal plane. Try hand holding from the base some of the most popular lenses like the 70-200 as an experiment.
