I have the 14-24mm and I don't really like the focal length. I am thinking of switching to a 16-35mm lens and I don't mind switching system.
So which is the best UWA zoom?
1) canon 16-35mm f2.8LII
2) sony zeiss 16-35mm f2.8
3) nikon 17-35mm f2.8
Is there any review that compares all these three lens?
