This is a list I made when I was making the same decision a couple years
ago. Some of these points may only apply to the 7e body, and of course now
there's the 70-200 f2.8 with IS.
70-200 f2.8L
Pros:
1. 2.8 maximum aperture at all focal lengths
2. very sharp, highly rated lens
3. can use teleconverters
4. 2-touch zoom
Cons:
1. shorter focal length
2. only center focusing point with TC
3. no ECF with TC
4. have to add TC
5. no IS
6. slow auto focus with TC
100-400 f4.5-5.6L IS
Pros:
1. 400mm focal length
2. image stabilization
3. don�t have to add TC
4. ECF at 200-400mm
5. fast auto focus
Cons:
1. smaller maximum aperture
2. can�t use TC
3. push-pull zoom
I went with the 100-400 f4.5-5.6L IS. Happy shopping!
