Originally posted by SharkyCA I think I covered all the cameras effected with the poll options
K-500 is missing, but this was a pretty short-lived low volume camera.
Originally posted by SharkyCA I am trying to get an approximate time span that this problem has covered
2012 to recently i.e the production times of the affected cameras K-30, K-50, K-500, K-S2, K-S1, K-70
Originally posted by SharkyCA I am looking for the ones THAT HAVE FAILED
See list above. this is already well studied and known. These are the models that used the green Chinese manufactured solenoid in the aperture block.
K-7, K-5 line, K-3 line, KP, K-1 line all use motors in the aperture block and not solenoids, they are not affected.
Originally posted by SharkyCA It would be nice for Ricoh to acknowledge the problem
It's not going to happen. We may feel better as users, but business doesn't work like that. What they are doing is fixing a lot of them for free even out of warranty.
Originally posted by SharkyCA follow up with Ricoh/Pentax with regards to how many camera models have been afflicted with "APERTURE BLOCK" or "DIAPHRAGM CONTROL BLOCK FAILURES"
They know better than anyone, they have all the manufacturing data and warranty repair data.
I'm not against the poll, just pointing out that there is already a wealth of information on this topic in these forums.
