I'm having an issue that I'm sure some of you are familiar with who can perhaps point me the right direction. I just got the Canon 16-35 f4 which I'm using on my Canon 5D. Yesterday morning I started playing with it and it has some terrific capabilities except I'm getting strange results where there is a lot of blue sky. I'm assuming it has something to do with having a lot more angles of light coming into the picture as I know polarizer filters are sensitive to light direction. I had read advice to not use a polarizer filter as it made the ugly contrast worse. So other than limited what is in the frame any pointers for what is happening and how to avoid it or fix it?

Attached is a sample picture and you can see the dark sky which fades off into light sky around the edges. So far I have found it almost impossible to "fix"

No lens makes an image which is lighter at the edges, not even the superb 16-35/4L IS - so this has to be excessive vignetting correction. Try shooting RAW, and process without any vignetting correction.

The lighter colour along the horizon will have been real, I'm only talking about the edges of the frame..
