I wrote to Pentax France
about the SDM motor failure, asking whether there was a problem with the first manufactured lenses.
My DA* 50-135 lens was one of the first ones available in France. The serial number
of my lens starts with 900xxxx
Although I mentioned that serial number in my letter, Pentax France
didn't consider my specific case but stated that
Despite all the fuss done on forums, SDM failures are not considered as a hidden defect.
Lenses should be assessed on a one-by-one case.
didn't go further on its answer. Alas, the repair department didn't provide any explanation for the failure of my lens.
Once again, there's room for improvement
: terrible communication with customers but rather easy solutions to implement.
Any experiences from other countries ?
