Thank you very much for that information. You have actually confirmed my decision to buy the 24-70. I would love to eventually add the 16-35, but I think you are right the 24-70 will be my work horse and that is what I need right now. I absolutely love my 85mm L portrait lens, but I found myself needing more range with it, so I think this is the right decision. Thanks a lot, you hit the nail on the head for me!!
