I set this image up to capture adult Tree Swallows flying in to their nest box. This is a first try. Image created today at Sackville Waterfowl Park, New Brunswick. I prefocussed on a bird poking its head out the nest box hole, then waited for a bird to return using the same focus point. This is prone to some error and the focus wasn't perfect, just OK. This is my first attempt with the 1.4x tc so I am on another learning curve here.
