As here we are talking about profit side of hood, but I encounted the side effect too and it was almost lens\'s fatal destination.I attached flower hood to a zoom lens, after the session I didn\'n detached the hood and put them in the bag and let it lay on the backsit of my car.The position of the camera is paralel to the surface of the sit and it touched by 2 points: the base of the camera and the lowest petail of the hood.The road is long and bad.Got home, I detached the hood and feel the front group a little loose.Next day when I tried a shot, AF seem stucked to one point, motor still ran.Brought to repair shop, the service man said: broke AF gear, derailed front group from grooves.Fortunately, he could fix it.My lesson of hood is : when the hood is on I only hang the camera, beside me when walking or in car, never let it lay on the surface.Better detach it right after shooting.
