When I used to own both the 17-40L along with the 24-105L, I would sometimes use the 17-40 on my 1D Mark IV as a wide angle zoom. When I did so, I would mount the hood from the 24-105L on the lens, as it fit OK, was way better for protection, and actually fit in the bag unlike the awful hood that comes with the 17-40.
I moved to the 16-35 II, and since this lens has 82mm threads the 77mm hoods don't work anymore.
By getting a 24-70L II, I will get an 82mm thread size hood that fits on the 16-35 II when I use it on the 1D4.
So....good justification for a $2300 lens, or is this a stretch?
