Hi, I'm a college sports photographer looking to add a second body to my camera bag. I currently have a 70D, Tamron 70-200 f2.8, and sigma 17-50 f2.8. I was thinking either the 1D mark iv or the 7D mark ii as they both have 10 fps burst, good AF, and can be found for around $1,500. My concerns are that the 1D is getting rather old but the 1.3 crop would be better for sports like basketball and tennis for poor light and since I can get closer. The pro of the 7D would be that it has a 1.6 crop so for sports like football and baseball I can get closer to the action and I think the AF system is better.
Any help would be appreciated.
Thanks.
EDIT: Also the 1D has better battery life and I think is more durable but could be wrong (like water resistant).
