So I've had my Air 2S for about 5 months now, and I love it... coming from an Air 2. The one thing I'm not used to is the Auto Focus. I leave it on Auto, and I see sometimes that it will start focusing as I'm taking a picture. My typical use case for my 2S is sunsets, and I use 5-shot AEB. There are times when I see the focus changing as it's taking the 5 shots. So should I do the auto focus, then switch to manual before doing the shots? Should I leave it at Auto anyway? Wanted to get your opinions...
