What I meant is I control the shutter speed, choosing 750, or 1000 based on what my viewfinder meter 'tells' me and the autoISO would then adjust itself, usually to 1600, or 3200, or occasionally down to 800.
I've tried Tv mode but my keeper rate is higher when I do it myself.
As far as composition / style - basketball is not my usual sport, and I had a tough time on the ACTION/SPORTy moments, so I chose to go after the more personal / candid shots.
My volleyball parents always like to see the emotion of the moment, rather than the stop-action hand on ball so to speak. What I REALLY like about the 135 is the bokeh, really isolates the player IN the moment. Next week, I am shooting a VB tourney for 2 days, and I am renting a 1D Mark IV as a trial...trying to decide 1D MIV vs 1DX.....
