Really, I get to be the one to start this thread? I bought this lens a while back but only really took it out and tested it for the second time today. I like the results. My skill level has room for improvement in using AI Servo but where I had good technique (keeping the focus points on the same point on the subject) I had good results (see sample 2 below). I was also impressed with the closeness of focus at 18mm. All shots taken with a 7D Mark II at ISO 400.
