24 1.4L?
what do you even want the lens for, without a proper reason, it just becomes GAS...
I want a 70-200 2.8IS, because I shoot events, and shooting events with 3 prime lenses is a bit tricky, I also want a second body as a backup and so I can have 2 extreme focal lengths going at any 1 time. I want the 24 1.4 because i shoot time lapse so 1.4 in a wide angle would let me keep the iso low at night. I want the 17-40 because it's a great lens for event shooting on a 1d body and I don't need 2.8. I'm also contemplating the 135L to shoot concerts as 6400 iso on my camera isn't pretty so being able to drop to f2 3200 rather than 6400 2.8 would be so advantageous.
and i've been mulling this over for 2 years, i'm only 22 and fresh from uni so i'm cash poor, time rich, and fairly busy as a photographer- I figured out where my issues were, and I designed a lens solution to get over them
