X number of lenses are normally checked in a line but in this case, I am surprised that Sony isn't giving far more attention to QC. This has to be one of the worse rollouts of a product I have seen. Come on Sony.
What makes you think X number of lenses are checked in a line? I don't think that happens with anything but very expensive lenses like the Cine lenses at Zeiss and Leica M lenses. I think none of the typical DSLR and mirrorless lenses are checked in production.
At least in the past, QC checks would be that every 50th or 100th lens would be checked for tolerances. Not torn down but checked. The number isn't important, it is that they pulled lenses and did a QC check. That was how they verified that the line was doing its job.
Again what makes you think this actually happened? From Roger's postings at lens rentals blogs (and maybe he can comment more here), it seems to me he doesn't believe this happens with any manufacturer. Personally, I think it is an internet myth. How would they check it? Do they have a lens testing set up at the factory? I highly doubt that. Maybe, but I doubt even that, they make sure that it turns on, but I highly doubt there is now or has been any testing beyond that except with the very expensive lenses such as Zeiss Cine lenses and Leica M lenses.
