So, the saga continues...


At this point, the question is, "Is the 24-105 lens actually superior to the 24-70 when it comes to chromatic aberration beyond the focal plane, or did I (and a few others) just get bad copies of the 24-70?"





Now, I realize that this isn't an exact duplicate, as the natural lighting changed a little and I didn't hold the paperclip exactly the same, but I think the results are still valid, particularly since I tried this several times and got similar results on each...





Both at f/4, both at 70mm focal length.


I'm wondering if Canon is going to give me an excuse, admit to the particular design shortcoming of the 24-70, or actually step up and fix the damn thing.
