Alright everybody, here's the hard question. Someone's gonna ask it! 
You can only pick 1 lens for the rest of your life from today's current lineup. What do you do?
Take some time and think about your answer for
1. A Crop Sensor camera
2. A Full-Frame camera
Also, let us know what you normally shoot (weddings, landscapes, macro, etc.)
I'll start it off:
(I shoot Weddings and Events, primarily)
1. EF-S 17-55mm f2.8
2. EF 70-200mm f2.8 II (amazing lens)
