Would like to hear thoughts and opinions on this. 
I'm thinking of selling my 24-105 (+ a 50 prime possibly) to fund a 16-35, I just want something a bit wider again as I used to have a 17-40.
Not sure if I should save up and keep the 24-105, or just sell it? It is just such a convenient range - although f/4 can be limiting when shooting indoors so I usually use something else then. My concern is I might regret not having it, currently have: Sigma 50, Zeiss 50, 100L, 70-200 2.8, 300 f4.
.
. Is there some reason you have the two 50's? I'd imagine the Zeiss is significantly sharper.
