Hi I am going to my granddaughters gymnastics event tomorrow. I have a D7000 and 18mm-105mm kit zoom lens and a 50mm 1.4. What would work best and no flash is allowed? Some of the event is at the farthest end of the gym. What setting would you use? I am thinking ISO 3200 to 6400. 2.8 and 1/640 speed.
Thank you
