try 1/1250 at 2.8 and meter it with a light meter
Ill bet you can go 2.8 1/1250 at 2500 or 3200 and it will be sharper
not that its bad
One thing I'm going tol have to do is put a piece of gaffer's tape over the small wheel on my battery grip. Shooting with two camera bodies when I sometimes put one down next to me to pick up the other one, I hit the wheel on my leg raising my shutterspeed by accident. I have to keep checking to make sure my shutterspeed hasn't changed and sometimes I forget. And when I do check, I see I shot ten photos at 1/2500 or something like that.
1/1250 at 2.8 would definitely work. I'm usually shooting on auto-ISO.
