Hi, I recently sent my 17-40L (about 10 years old) to Canon to have them clean it and adjust it since the zoom ring was loose and the focus ring felt a bit gritty. It came back looking almost brand new after a week.
I mounted my 5D3 on the Gitzo 3 series tripod (RRS head) and shot an image with it and another with the 24mm TSE-II which I love and use quite a bit. The settings were identical (iso 100, f8, 1/400) and the processing on Lightroom minimal (no lens or CA corrections) and identical on both images. Any color differences are due to the way the lens renders the image. The 17-40L is noticeably warmer than the 24 TSE II, which is a bit more neutral.
Honestly I was impressed with the 17-40L. Even up to the very edge of the image, when viewed at 100%, I cannot really tell the two apart in regards to resolution. It is that close. (The 17-40L was set at about 25mm to get almost identical angle of view).
The first image in each pair is from the 24mm TSE-II.
