Today I was working on a photograph of an old building from China Camp, California:
As I worked on it I realized that it could provide a reasonably good sample of the performance of the EF 24-105mm lens in one limited case on a 5D2, so I sliced it up and made the following sample:
Depending upon the resolution of the screen on your computer, these crops represent a photograph that might be a print of between perhaps between 60\" and 84\" wide. It would be a pretty good print. (I typically crop to a 4:3 aspect ratio. In the small version of the photograph posted above, I chose to crop mostly from the left side. You can still see the bit of the rafter on the right side in both examples. The image was not cropped vertically at all.)
I have no illusions that this example is \"proof\" of much beyond the limited case it shows. However, 100mm is not usually regarded as the sharpest focal length on this lens (that would likely be around 50mm), and this turns out pretty well even in the far corners.
