17-35 AFS or 28 1.4D?

I currently have a 17-35 AFS.

I shoot mainly landscapes~sunrises-sunsets with it.

The 17mm end always seems to wide and on wide shots at tghe oces, you definetly pick up the curvature from the lens (yes I know that I can straighten it in photoshop and NC).

How does the 28 1.4D fare as a landscape lens and all around...is it more versatile than the 17-35 due to it's lower light abilities?

Opinions?

Hi Bjorn...

I guess my real issue is that I use the 17-35 mostly for sunsets / sunrises and landscapes and I quite honestly fins that it is TOO WIDE for many of my applications. The areas that I shoot don't lend themselves to zooming closer with my feet and I'm now wondering if there isn't something longer that might suit my needs. I could sell this in a heartbeat and perhaps buy a 45P or even one of the 50mm lenses and have some cash left to put towards more long glass for my wildlife shots.

Additionally, while the distortion is fairly well controlled on the widest end of the 17-35, it is certainly there.

In your opinion, is the 45P any better / worse than the 50 1.8 / 1.4 for this application? I had a 45P previously and found it to be sharp...rather unobtrusive, cool and it gave good shadow details. I never did try it in this specific application however before selling it.

Thanks in advance....
