LD not necessary means better performance, lots of new Sigma Zoom
claim APO design, but I got a 75-300 APO that was really bad at the
long end. Have you did any comparison between Zuiko 180/2.8 and Tamron
180/2.5? I think Zuiko 180/2.8 might lost on the chroma (as it is
really bad at high-light area) but the resolution and tonal rendering
of Zuiko 180 is great... okay you may know more about the Tamron.
