‘Caught Off Guard’ would be better name for this article. My shutter speed was 1/125. A little slow for the turtles here. I had been using this lens all of about 3 hours too.
This is ‘panning’. I moved with the bird and a good thing I shot the wings on a downward slide. The background blur shows just how slow I was and fast the bird was. Panning is much more effective with a moving car, bike, something faster than this.
A fun shot…only because I caught him.
