Erwin is now reporting that he will make an updated version of his Leica

All different optical designs. All are Gauss derivatives. #1 is an
8-element, #2 and 3 are 6-element with slight differences (in #2 the second
and third elements are cemented together whereas in #3 they are separated by
air, sometimes called an "air lens" for the different refracting effect of
air vis-a-vis glass,  and #4, frequently referred to as the "pre-aspheric",
is 7-element with elements 2 & 3 and elements 6 & 7 cemented together. If
you're really interested in this stuff, Erwin Puts' book, "Leica Lens
Compendium" is an excellent resource, though in it Erwin occasionally
expresses opinions with which I have disagreed publicly. Seth
