I have a 16-35, 24-105L and 70-200 f/2.8 just got this one. I can shoot almost anything. If you have that kind money though I would buy 200 prime f/2.0 and every 100mm step above that to 800mm and there ya go. If it is on this planet you can shoot it. That is way too much to take on but hey if your up for the challange. Other wise i would take Eric's advice and get the 24-105 to see what you like to shoot. Wish I had your kind of money.
