Though the gear I use continues to be updated here is the current setup and why.
Canon 17-40L --> Ultra-ultra wide effect on the 5D ii, works in close quarters or for venue shots
Canon 24L --> Fast wide prime for low light, though I like it best on the 7D for a walk-around, and ceremony
Canon 35L --> Beautiful colors, well fitted for either the 5Dii or an APS-C, great for walk-around and pre-ceremony
Canon 70-200 2.8ii --> My most used lens on the 5D ii, usually fast enough, and great auto focus speed
Canon 85L --> Beautiful portrait lens, wicked fast f/1.2, but often quite slow to focus, typically post-ceremoy
Canon 100L Macro --> Ring shots & various details, typically pre-ceremony
I hope this helps!
For the first one or two, I used only the 17-40, 50 1.4, 35L, and rented 70-200
