I'm having a rather difficult time deciding which lens I should next save up for. I've been looking at the 100-400mmf/4.5-5.6 L IS USM, and the 70-200mm 2.8 L IS USM. I'm going to be using this lens for shooting sports and wildlife. If I was to choose the 70-200mm I would use it paired with a 2x coverter for wildlife, likely.


For wildlife, my eye immediatly turns to the 400mm, simply because it gives me more range and I already have the 2x converter if I need to extend it even farther. However, it seems too slow for sports if I'm wanting to stop the action.


I'd like to hear some other peoples opinions before I make my own suggestion, so if you have one please share it.
