I will be the school photographer at a small private school this coming school year. I have a 7d with the following lenses: EF 50 f/1.4, EF 70-200 f/4 IS, and EF 17-40 f/4.


The vast majority of photographs will be taken indoors, and sometimes I won't be able to (or want to) get too close. The 50 f/1.4 will obviously be useful, but it doesn't have the reach for most sports and many all school events (and sometimes I am frustrated with its results).


I have read great reviews of both the 85 f/1.8 and 100 f/2. Which would you choose? Is the 85 too close in focal length to the 50?


In my experience, especially at this school, f/2.8 just isn't fast enough in many situations, so I really want the flexibility of a faster lens.


BTW, I know the 70-200 might be useful in some situations. But kids move a lot, and I just won't be able to stop motion at f/4 indoors.


Thanks for your help!
