Ah, the challenge of trying out for soccer! The kids don’t really know the difference between a game and a “try out”. (I’m sure everyone who wants to play will be able to play.) I’m no soccer player but, to me, all were equally skilled.
For outdoor situations like this, I always choose my Canon 7D and the 70-200mm zoom. This particular shot was taken at ISO 400, f5.6 and 1/400 second. The somewhat slower shutter speed than might be expected for a bright mid-morning day was due to using a polarizing filter that was probably not needed.
