Good job, as I've taken over a thousand pictures in the past week!
Yeah, it's quite difficult to keep steady at full zoom, but having the shutter speed fast enough, and the appeature wide means you still get a crisp picture (providing it's in focus). I was reading in a book that the safe shutter speed is worked out at by zoom length divided by 1, so at 200mm, the slowest speed I could use was 1/200 second. At the other end for the 55mm, it's 1/55 second
