Right now I have a Canon 5D Mark III , a 70-200mm a 24-70mm and I plan on getting a 100-400mm. I guess my question is will this be enough to shoot college football ? I also have a t5I that I got some pretty good shots of high school football paired with the 70-200. I was thinking of maybe getting a 7D Mark II to put the 100-400 on or would my 5D be ok? Another thought was to bypass the 7D and get a sigma 150-600 sports lens for the 5D and just put the 24-70 on the t5i for endzone shots. I'm really not sure if I have a question maybe just some advice and or suggestions.
