Thanks for posting that. Roger's reviews are the most informative.
Overall I am a little disappointed. I use the old lens mostly for portraits so center quality is most important to me. Based on this review, if I buy this lens I might actually lose some center sharpness.
I do wonder if the less quantifiable qualities (bokeh, chromatic abberations, ...) ale improved.
Maybe I should just get the 35mm f/1.4 for my rebel.
