I would like to know which one of these two lenses is your favorite? I have compared specs. and notice that the Sironar-N is much heaver? Why? All specs. seem to be the same otherwise.
I don't want to hear about similar lenses. I am ONLY interested in a comparison between these two optics (or three if the comparison is between 480mm APO Symmar, 480mm Symmar-S and 480 Sironar-N).
Thanks!
