K-30 shutter life expectancy You cannot seriously expect to estimate shutter life, before the cameras start dying of natural causes. There is no data to suggest his experience is above average. That poll you quote has design flaws so serious it's useless, and was the day it was published. Only a controlled group of randomly selected cameras with study size of say a 25-200 could do that. That study is just pure anti-Pentax propaganda repeated ad nauseam by disgruntled users.
The study is actually a perfect example of how people using legitimate research tools can effect the research outcomess by using selective test subjects. A favourite trick of drug companies to prove the effectiveness of useless drugs, such as cholesteraol drugs. It does make drug companies billions, but it's really shoddy research.
This poll was nothing more than bunch of disgruntled customers who got burned in by a 10$ part taking out their frustration on Pentax.
You can't compute life expectancy if all the healthy subjects aren't dead. Please don't continue to point to this nonsense.
If our OP was in that poll, his 91,000 clicks wouldn't have counted, because great number of them occurred after the poll was taken. Whatever he'd taken at that time would be in the poll, which would have been a gross misrepresentation of his final shutter count. When the collection methods used to obtain your original data are unreliable, so are your conclusions.
The fact that a person can get 90,000 clicks from a K-30 is all the proof you need of how inaccurate that poll was. That shows what the camera is capable of, as was shown in the original page. What was the only inconclusive part was what percentage would reach that level, and that will continue to get higher and higher as the K-30s get older and older.
It's odd that this poll is referred to, despite the fact that the defficineces were pointed out at the time it was first discussed. it just shows, people can't tell the difference between good research and opinions masked as research. But for you who fall into that category, the government drug licensing departments can't either. People who make really good money for evaluating research make the same mistakes.
Good research is rarely all that sensational. bad research seems to hag around forever.
