Originally posted by normhead I find it interesting that people claim any part in any manufactured item can be 100% in fallible, especially a moving part. That's just disinformation. If it moves, sooner or later it will fail.
Of course a solenoid ain't no perpetum mobile, but we have facts, i.e numbers:
The original Shinmei Solenoid, when manufactured in Japan, had a much higher actuation/live-time than the China version.
We won't go into detail here... believe me, it is better so!
On the other hand, this is just to easy: With the Japan made solenoid we have zero failure reports!
That is a very clear fact. Nothing needs to be added.
And we have Pentax bodies going into very high shuttercounts with this solenoids. Very high!
My own experience:
From now at least 50 x solenoid changed myself within family, for friends plus many more (I encouraged others to buy defunct K30's, 50's etc. and to repair them for a bargain) I can say for sure that never ever one of those solenoids failed and I know with 100% certainty why.
Originally posted by normhead This report is 100% useless concerning this very issue of the China made solenoid.
Originally posted by normhead Look at that, other cameras fail, not just Pentax's. Read the comments.
Yes, that is very normal.
But the rare in failing until December 2015 due to the China-solenoid was pretty high.
Nobody knows the real failing rate.
But this number, if applied to the solenoid:
Originally posted by normhead 10% justified and 90% an over reaction.
