These were all taken at 1/640 - yes were cropped but there is motion blur. I take a lot of tennis photo's and like the motion blur. Do you think it is effective or not?
Those are fine, fine photos. As per your question, I do both blur and freeze shots. It's tough in tennis to do freeze shots. If you have the chance, go practice at 1/5000s. I found that even 1/2000 isn't quite fast enough. I take a tele, get far away, widen the aperture, set shutter to 1/5000s and auto ISO, and blast away. Sometimes auto ISO isn't good enough. I have to shoot in Av mode with ISO safety shift, min shutter speed 1/5000, auto ISO, EC +2/3. My aperture can run as low as f/2.8 in this situation. You just have to experiment.
I do, like the motion blur shots too. And the fact you got Djokovic too, really cool!
