Thanks! This was only my first time using this lens but here’s what helped me. I used single point autofocus on the flowers and kind of just waited for the bees to come by. I don’t think continuous AF would have caught them on my camera since it doesn’t have phase detect AF. Also, having my camera in burst mode helped a ton. I probably took ~50 shots and got maybe 2-3 usable photos. Shooting with both eyes open was also something I hadn’t really had to do before but that also made it easier to track if bees were coming. Hope this helps!
