Out of your choices I'd go with the 16-35 over the 14mm, then sell the 17-40. In my opinion the difference between 14 and 16 isn't that large and the IQ is pretty close if you compare them on Bryan's charts. Plus the range to 35.


But real world, I'd agree with Mark and say go for the 100-400 to fill your wildlife needs and the 17-40 is really good lens for you landscapes.
