This lens continues to amaze me. I've had the chance to use it since August (long term loaner from CPS), and in my opinion, the 1DX/200-400 combo is the best out there for sports photogs at the moment. It may not be the best in absolute dungeons, but it's just so versatile.
Here's a few from swimming. Light isn't too bad (better in quantity, not quality). I was at ISO6400 and 1/1000th for these, with some correction in post. I think this is my 3rd time shooting swimming. I need to practice with it some more for sure.
Let me know what you think.
edit: Just realized my thread title is very poorly worded, haha.
