I am very glad to see the moderation of the postings to avoid tangential ad hominem thread-hijacking when what we need is real data, as we learned in 8.01 etc. FWIW, I did some test shots with my 250mm CM-W Fujinon of images with out-of-focus highlights, looking for the reputed onion-ring bokeh that the digerati believe to indicate aspherical elements but saw nothing out of the ordinary.
