Trying to catch these in flight is by chance... well almost... there's ways... Their flight is like kid in a candy store.. never know which direction he's going or which jar he is going to stop off at. Sharpens up your photography talents. Using the Tokina 12-24 is useable as I have a full frame body... sort of...18-24 of it.. You can still use the rest but you loose quite a bit...
