Why? Is there an observable difference in QC between facilities? My assumption would be that the lenses from the Vietnamese production facility would be on par with what has been produced in Japan, unless there is evidence to the contrary.

IIRC there were some QC problems when the manufacturing/assembly of Pentax lenses first moved to Vietnam. This corresponded somewhat with the initial SDM lenses which were not trivial. I am not sure if it is still an issue.

Other companies (Nikon I believe) have recently shifted manufacturing/assembly out of Japan.


Gotcha. I wonder if the QC problems were design, component, or assembly related?  I only owned one SDM lens, thankfully without issue, but I do recall there being a slew of complaints about failure within a year or two of purchase. Were these problems associated with early batches of the tech implementation by Pentax, or was it ongoing?  I’m largely ignorant to the details, so I’m curious.
