I thought they are pushing out version 2 of the lens ... so fast {:4_93:} "50/1.4 ASPH was in fact APO ..."
What does that mean ? He said 50mm 1.5 ASPH is an APO design. Lens can be design to Apo spec, but manufacturing process limits it. As remember from Peter Karbe, he said 50/2AA cost up in manufacturing than the 50.4asph. Glass technology is more advanced in 50.4asph.
