What's interesting is that despite the "Sonnar" name, it is not in the
Sonnar configuration, which can be described as a modified Triplet, with
cemented doublet, or triplet in the middle, and a singlet, or a cemented
doublet in the back.  The configuration is pretty unique, though resembles a
Tessar, with a cemented doublet behind it.
