Originally posted by martin42mm It will be interesting when we have some data on the 'upgraded' Chinese solenoid that Pentax are reputed to be using in the current K-70s, and how they are faring where reliability is concerned..
If "data" means just statistics, those we have already:
The K-70 is now almost 6 years on the market, June 2016 it was introduded and it was a hit, many were sold.
So it was the first Pentax with solenoid that right from the beginning received the modified China-solenoid. That is more than enough time because we had good data with the K30 and K50 to compare. K50 manufactured for 2 1/2 years, K30 only 1 year!
Both, the K30 and K50 showed first signs of ABF after 1 year and a strong ongoing statistic by registered users of a German Pentaxforum showed:
- From 219 K30's 150 failures = 68,5%
- From 149 K50's 75 failures = 50,3% (not a single K50 manufactured post 12/2015!)
- From 53 K70's 7 failures = 13%
(
all of those in the first year since introduction on the market,
none after April 2017.... so no more failures since 4 years, a very strong figure!)
No survey for K-S1 and K-S2 but my personal experience is that the K-S1 has figures as high as the K50.
I repaired more K-S1's than K-50's!
K-S2 less, quite a few were still manufactured after 12/2015, I had only one of those for repair.
But ... actually this is a K-70 theme and in future belongs into the K-70 section.
