Hi This year I can afford to add either a D4 OR the 300mm f2.8G but not both. So I'm debating on which to buy first since my funds are limited. I have a D7000 and shoot 50% outdoor sports and 50% indoor at 6400 iso (no flash permitted). I have some good glass with the 24-70 f2.8 and a 70-200 f2.8 as my main sports lens.
Any opinions from the D4 users which way would you go first?
