si merece la pena o no es una cuestion muy personal.
pero si q hay otras opciones y ken rockwell, que aunque ya sabemos que sus comentarios los hemos de tomar con la precaución que da la sensatez, las muestra así:
"If you're a cheapskate and/or appreciate professional build quality, the 20-35mm f/2.8 AF-D does the same thing, with smaller size, less weight and it's built to professional levels. The 20-35mm skips the alphabet BS convenience features like VR, AFS and stupid-wide 16mm to deliver pro-quality optics in a pro-built lens for half the price (used).
This said, for most of us reading this, this 16-35mm is the sharpest and best-handling ultrawide zoom ever made. Get the 17-35mm f/2.8 if you need solid metal or f/2.8, otherwise, I'm going to grab this 16-35mm long before I'd use the heavier 17-35mm again.
The huge 14-24mm is a special-purpose lens. I don't suggest it for general use; I suggest this 16-35mm. "
