Two element. <http://www.angelfire.com/ca/erker/closeups.html>
As it says, though, I believe 2 element is acro, not apo. Not even sure if such
designations are meaningful in context,
as the lenses they are put in front of are usually not apochromatic.
I wouldn't mind having one, but have probably not looked very hard.
I have the iS/L Lens A-Macro and B-Macro, but have seldom used them what with
the true macro lenses lying about.
