All I know about lens design and aberrations - which ain't much - came from
"The Manual Of Photography" (Focal Press) and a couple of Feininger's books.
It was just enough - any more would have had me snoozing.
Like you, I've been perplexed by Olympus' ability to get away with what
they've accomplished in their lens designs. But I'm not complaining. If it
works, great.
BTW, you missed a very recent thread in which CH Ling and David Irisarri
discussed their findings regarding chromatic aberration in the Zuiko 180/2.8
- the thread may be in the archives by now, or will be soon. Interesting
stuff, plus photos on their websites demonstrating their observations.

...I'm curious how some
Zuikos are made without the aid of a single achromat doublet (the
cemented lens pair commonly seen in lenses, considered a standard way of
reducing red/blue fringing), and yet seem to have no difficulty with
chromatic aberration (I believe the 135 f/2.8 and the 100 f/2.8 are
examples). And, also for example, I'm not all that swift on my knowledge
of aberrations in general. Does anyone have a website or a book to
recommend, that takes a layperson into a deeper understanding of lens
design, and the tradeoffs involved in designing a lens?
