If you have 50mm as your widest lens, you are missing out on a huge range of focal lengths.In your position, I'd get the one I need.
Only you know which, you did not give anyone a hint as to what it is that you currently photograph, or problems you are having.
i photograph everything.
i want to be able to have this range covered. i don't want to be pinned down to a specific use but rather to be used for a broad range of applications.
I'd get the 24-70L MK II. I have the 35L and 24-105L, but am going o try the 24-70 to see if I can get by in low light. It might be difficult.
I won't sell my existing lenses until I can see how I do with f/2.8 and extreme low light. I will be at ISO 12800 and maybe higher.
thats more the sort of reply i was after
yep as I said in my opening post the whole point of my purchasing one of these options is the very fact that my widest lens is 50mm and this needs rectifying.
i have to say i am really leaning towards the 24-70 II considering the mostly positive reviews it's had.
