This past weekend I got my new 100-400mm L IS II and immediately shot off a round of photos to check it. I notice that there is CA at 100mm (both green and purple), visible only when viewing at 1:1 or 2:1 (very visible). The CA occurs at any aperture at 100mm, but not at 200mm+. My 70-200mm L IS II does not show CA at any length. Did I get a lens that is, perhaps, poorly aligned, or is this simply an unrealistic expectation of pixel-peeping perfection? I realize that this can be easily fixed in PP, but if the lens is out of alignment, I would prefer to get one that is better.
Thanks for any help...
