It's time to buy a new lens for my XTI again. The lenses I'm considering are the
EF 70-200mm f/4 L IS USM,
EF 70-200mm f/2.8L IS USM,
EF 100-400mm f4.5-5.6L IS USM , or maybe, MAYBE, for the sake of image sharpness,
EF 300mm f/2.8L IS USM. I'm planning on using them for outdoor only lenses. I have indoors covered with the two lenses I have now. They will be used on animals, people, etc, as well as with a tripod. I'm hoping to hear from people who own/have used any of these. Any opinion will be extremely helpful. It's not every day I dump this much money on something.
