Thanks for sharing!
I just "liked" your post.
I hope I'll never have to fix my FA 77/1.8. I'll watch for a lose focus ring.
I'm with you regarding QC. If Ricoh could improve QC and maybe iron out some systematic problems (16-50 & 50-135 SDM) so that people can buy expensive Pentax equipment with more confidence that may make quite a difference in the long run.
Currently, I would only pay MF prices for a 16-50 or 50-135 zoom. There seem to be users that have no trouble but the frequency of which one hears about SDM problems even after repairs (typically out of warranty then) is just too high (for my taste).
