Originally posted by GerryL These things are mass produced and I wouldn't think they have to calibrate each lens.
Manufacturing standards nowadays are very precise and calibration may be done at the start and everything done automatically after that.
There would be random sampling every now and then to check quality but that would be it.
The only thing they would actually save on is the additional ink for the silkscreen process.
My money's still on a calibration issue ... there's actually additional cost to
not ink the focus ring on the DAL version... if the DA and DAL are the same lens except for no hood and plastic mount, why not use the calibrated focus ring on all of them, instead, Pentax has a printed focus ring and an unprinted ring, and the additional time overhead to load the correct ring for a certain X number of unit production run.
Sorry to the OP for going off-topic here
