I was seriously considering the 400 for sports and other photo taking chances, such as birds. I had a chance to try the 100-400 and I know the quality is pretty comparableto the 400 prime. Anyway, long story short, sitting on the sidelines of a little kiddie soccer game, I found myself to be more in the 300 range. I think that might be the way to go so I am going to give that a shot. Thank you for all of your replies, I really appreciate it. I also thinking that the MFD of the 300 will be a bonus. I didn't think it would be initially, but after a weekend of pure shooting time, I noticed that I did shoot many things at the MFD of the 70-200 and thought I would like to have my macro. I believe my choice was made with those two situations. 300 F4 IS it is!.


Again, thanks for the input everyone.
