Hi, how do u keep ur lense at 300 mm lens position when positioning 90 degress for a moon shot. Other than holding on to the zoom ring, which will cause shaking, I've no idea :dunno:

Well, I guess keele dun't understand my question. I mean if ur lense is position 90 degrees to the sky, how do u keep the 300mm from sliding back to 70mm?
