I am a sports photographer and mainly shoot baseball. I have a 70-200 2.8 on a 1d mkii.
My question to you, going into this spring, I want to either purchase a 300mm prime or a 7d.
The 7d will help me more for night games because of the extra ISO but the 300 will help me get tighter shots, but I will be limited light wise.
Probably 40% of available work is under lights.
I am going to have both by mid season, but am agonizing over which to buy first.
The 7d paired with the 300 will give me some tight shots and the 1d with the 70-200 is going to be nice for everything in between.
What say you?
