Thx. I'm sure you'll be surprised to hear that swimmer is actually a beautiful 17-year-old girl. Swimming is amazing, as she looks so strong and fierce, and is really stunning out of the water -- probably the prettiest one sees in a given day...
I'll try dropping expansion to see if it changes anything.
Ok, I made two changes. I turned off the expansion, but from chimping, didn't look like that was the problem. I changed C.Fn III-2 to fast from slow. I had it set to slow per the "Guide to AI Servo AF Custom Functions" where it said to do so for swimming. Swimming is predictable enough that I'm able to keep the focus point where it needs to be at 200mm.
Not focusing on the drops here. I think I'll be able to notch up my quality a bit again this time around. Not that the parents seem to care -- they were loving the soft stuff out of my T2i -- but the 1D3's performance has been a dream for me, and I can see the difference.
This is my 11-yo son getting some laps in after an electrical storm cancelled his meet the previous day.








The AI Servo is very unstable and varies between front- and backfocusing with all lenses. 1-2 og 10 shots is in focus-ish. All lenses works like they should on my other cameras. Think I´ll say RIP and replace it with a mkIV. Anyone know the cost of repairing the AI Servo?
