Therein lies a tale. The first raptor I ever captured with a digital camera (an S5 IS) was a Northern Harrier. I was so happy. I just panned at his speed, and voila! Well, I thought it was going to be easy. S3, S5, SX10, SX20, and SX40 and I've been lucky to get three in flight shots of anything! This is gorgeous, but I'll plod along.
