When you ask somebody how to get from New York to Washington is it not logical to assume he will provide a fairly direct route instead of guiding you through Las Vegas?
Anyway, asking you again:
What other ways do you suggest then?
Quote: So you agree with me that there is no proof and you go even further and state that proof is impossible to obtain, but you still insist on knowing something without that proof?
Let me qualify that as you seem hell-bent on misinterpreting my position.
It is not in our power to obtain absolute proof as that would require data that Pentax won't release. You know it, we know it.
Still, based on the data available, we can be near certain that there is a problem with SDM.
The fact that you seemingly require us to produce absolute proof doesn't change that.
Do you follow so far?
Quote: Of course it is fine if someone personally decides not to buy an SDM lens because they are "near certain" that it isn't a good idea. But I don't think it is fine if someone spreads news about an allegedly "know problem" when all they have is circumstantial evidence that isn't suitable to create something even close to "near certainty".
You say there isn't enough evidence to get to "near certainty", I and most other posters in this thread seem to think there is.
Obviously when things go from "possible" to "more likely than not" to "near certain" to "very certain" etc. is somewhat individual.
What is your estimate of the probability that SDM lenses have two times or higher failure rate than non-SDM lenses in the first four years of ownership after the one-year warranty period?
Based on the information available, my estimate is 99%+. What's yours?
