Hi, This may sound dumb, but when do you actually fire the shutter with the 28-135 (or any other) IS lens. I just got the lens. This is what happens: 1) depress shutter button half-way; 2) lens makes noise, sometimes for several seconds; 3) lens stops making noise and the viewfinder image 'jumps'. Do I finish depressing the shutter during 2, or after 3? Or am I missing something here? It seems as though if I wait until the noise stops, then the lens will blur from camera shake (IS stops). But if I trip the shutter when it is making noise (stabilizing?), how do I know when?
