    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

Hey all,

Was looking for some insight on the aforementioned (in the subject) wide angle lenses. I shoot on a 5D Mark III, and am wondering if the f2.8 16-35mm is considerably sharper on the edges compared to the f4 17-40mm. I would be using the lens for primarily outdoor landscape use, but definitely would be used diversely. Any comparison of the two is appreciated.

Cheers!
