Thanks for your opinions everyone; it seems like I'll probably rent the lens for a week.


John, I do understand your philosophy of getting a fast zoom, but I'd rather buy the 24-105 for its build quality (yes, I do have L disease) and then get a 50 or 85mm prime for lowlight.


I considered the 24-70 but lack of IS and weight dissuaded me. I know there will probably be an IS version but it'll cost too much ($1800?).
