The 16-35 definitely covers a wider range of focal lengths, which is useful for certain purposes, but the 14-24 is theoretically better in every aspect except for the focal length in the long-range. Here's the main question: would a photographer get the 14-24 for the wider focal length and better performance, or would a photographer get the 16-35 for the versatility in focal length? I'd definitely pick the 14-24. Any day. It just offers so much more!
I don't see the photojournalist crowd going 14-24. Everybody else (who can afford it), hell yes!
