First of all, the following survey results once again verified that SDM is indeed rather unreliable and vulnerable to break, although some fanboys would still argue that the sample size returned in that survey is yet "not enough to prove anything"!
http://www.pentaxforums.com/news/pentax-sdm-failure-survey-results.html
Quoted:-
"What is a little bit more alarming is the fact that three of Pentax's most popular lenses seem to have problems with SDM reliability."
Well, how dare PF is to make a statement like this?!
"If you're frightened by the AF issue, then Sigma has readily-available alternatives to all three lenses: a 17-50mm, 50-150mm, and 17-70mm."
My pardon? Are that Pentax glass so easily replaceable? And what's the point of using Pentax bodies but Sigma glass?!! >:-(
Btw, if there are still not enough of the reported cases, just view this online Pentax SDM Petition, then you should be convinced, if not yet!
Next, there is a new comparison review of the Pentax DA14/2.8 Vs the cheapo Samyang 14/2.8 lens. It is tested that there should be a design deficiency of the Pentax lens that the field curvature for far objects is always greater than DoF(!?) so that the whole frame of the image is always not sharp at somewhere in the frame, no matter how and where the user focused! :-o I now know why Jun was forced to retire after creating this lens! ;->

who will answer? depending on the functionality and age of the product-sample.
the problem is not the survey sample size. the problem ist the kind of survey.
kind regards
ps.: btw: none of my sdm-lenses failed, so I had no reason to participate on the survey

Incidentally, I find the comment "although some fanboys would still argue that the sample size returned in that survey is yet "not enough to prove anything" a little mystifying and quite unnecessary. I thought this was a site for people that actually liked Pentax cameras and lenses.

"Pentax ranks highest in online buyer satisfaction with a score of 899 (on a 1,000-point scale), followed closely by Nikon (891) and Canon (888). Pentax performs particularly well in durability and reliability; variety of features; ease of operation; and shutter speed/lag time, while Canon performs well in the picture quality factor.
"Pentax's customer base has shifted since 2011 from casual photographers to those who consider themselves semiprofessional or professional photographers," said Sara Wong Hilton, director at J.D. Power and Associates. "In fact, across the industry, the results indicate a slight increase in self-identified semiprofessional photographers, possibly leading to the purchase of more high-end camera systems.""
This is JD Power performing the survery, not the amateur attempts at PF.
But of course, Rice would ignore any good news about Pentax from a reliable source. It would take away from Rice's time to keep beating the dead horses of SDM and PF.
