I took a 300mm to the Bees (AAA) game, intending to shoot some motion blur baseball action.
We saw some pitching.
And some hitting.
Shutter speeds 1/10 - 1/30.
In the last image, hitting, the ball leaves a trail as it changes direction through impact. It's the precise timing I was hoping for, (very difficult), but it's not sharp enough. Next time: tripod.
