If I remember the lens diagram from KMP, the A 15mm's aspheric element was
one of the smallest ones, in the rear part of the assembly, and thus
propably able to be produced by the glass-only molding (?) method described
earlier in diff. thread, used for small diameter elements such as in
microscopes. Or perhaps not - this's jsut speculation on my side.
Damn you all! You are making me want to buy the lens too! Now I have to
choose: Either a Z1p or FA* 24/2 ;-{
