Not to be rude Mark, but

Not a problem. I am the king of looking at how sharp a lens is in the center and overlooking the corners. Next September I will be going to Alaska and wanted my 1DmkIIn for the speed of AF and frame rate for any wildlife I see but also need to be able to shoot some landscapes. My 24 just is not wide enough for landscapes on this body so I purchased the 17-40. Most of the time I am shooting this wide it is for landscape and I usually vignette them in post so the corners are general not a problem for me. I decided to do some simple testing today anyway. Here are the results:

5D @ 17mm f4.0

I also have similar images @ 40mm on my flicker page. I loaded full file to my flicker but can only view 1024 x 683? When I look at others on flicker I can view full size. I do not know what I am doing wrong.

Enjoy
