I just rented a 50mm 1.2 L for this past weekend and the CA with this lens was just absolutely terrible. Many have told me that this is a common issue with this lens. My friend rented a 70-200 2.8 Mark II and he was telling me that he had to color correct all of his photos. Are these L Lenses up to par or are they junk? I have the 24-105 L and it's perfectly fine. Nothing wrong with it at all. I was under the assumption that these L lenses were top of the line. Is it because we're dealing with rented lenses? I am tempted to bring my 5D Mark II to a camera store and try out a brand new 50mm 1.2L. I was planning on buying one but now, I don't know...
I've heard that too about the 50L - just something you have to deal with. As far as the 70-200 f/2.8, my wife & and each have a MKII and can only say this lens is the closest to perfection that we have ever laid our hands on. Color has never been an issue for us. Maybe something was off on the rental copy, or there are some exposure issues.
