I am totally fascinated by fastburst. You set it to take as many shots in as many seconds as you want. Each of them are pin sharp. I recently used it when the Queen passed by slowly and yes, some had her looking away, some with the window frame in the way, some had sun refelction, but the joy is that you delete them and have the benefit of using the best. Similarly when taking pics of fidgety children, with fast burst you delete the rubbish and keep the best. Blinking can be an issue, with fastburst you delete those where people blink.
