I love the 21 ZE, however I am a wedding photographer and I'm too nervous to shoot with manual focus during a wedding so I have decided to sell this lens. I've been waiting for over a year for Canon to release an updated wide angle (14-24L anyone ), but there has been nothing. I'm assuming that the 16-35L is the best choice for me if I need a lens for my 5DIII now, do you agree?
What do you guys think would be a fair trade? 16-35L II +$100, +$200, +$300, +$400?
