As someone who has lived in SA on and off for many years I can tell you Rico is right about the BMW's . I'm not sure how much of the cars are actually produced or sourced here , but they are certainly not just "assembled", that much I do know . As for Zeiss its my understanding that Zeiss have a permanent contingent of some 15 people[or thereabouts] in Japan overseeing and involved in lens production . Clearly , Zeiss take their quality and reputation very seriously . Their really isnt any truth in the German ones being better[just snob value] , in fact some lenses have been updated over the years and these would be better , in some respects , than the generally older german made ones .
