Anyway, a friend recently disassembled several FA consumer zooms and was horrified to find out large tolerances by design, alignment through shimming as a rule, high wear plastic guiding rails - all of these easily leading to misalignments of moving optical groups,
And this, Mr. Modo, is why manual focus lenses often offer better optical quality and/or superiority to AF.

With regard to manual focus lens collection, optical quality and/or superiority to AF is the classic fallback position.
