No you're absolutely right. If you're shooting at f/28 then yes, the 16-35 is a must. I was just saying, at such a wide angle, if you're only shooting landscapes, I think the 17-40L is plenty good. You're probably going to be shooting at f/8 or lower anyway.
Thank you very much, even if i use f8-f32 i still like to have f2.8 lens, and 10-22 or 24-70 [24-105] are all great as well for wide.
I found that all lenses are great for landscape if i stop down to f8 or lower, even kit lens perform great as well.
