Originally posted by Mushu I'm very sad that my K-30 after only 5 years or so got the dreaded aperture solenoid failure. I'm not going to do surgery on it so AFAIK it is a pile of junk to be thrown away. Shame on Pentax for knowing about this and not replacing it for free for their loyal customers.
Anyway, I'm looking at the Pentax K-1 Mark II DSLR as a replacement, but won't buy it if it also uses these crappy bits. Can someone tell me if it also uses this same solenoid that fails? Maybe it's time to sell off my lens collection and just move to another brand, but really not happy about that. :-(
You don’t have to perform any surgery.
My K-30 began to suffer from the “Dark Image Syndrome” after just
two years, so I began using old film lenses, and setting aperture at the lens, so it still takes good pictures, and four years after I started having problems, it still is not a “pile of junk to be thrown away” - certainly not like the two Canon Rebels which had symptoms of a processor problem before they
totally died and have been in the town dump for nine and seven years, respectively. In addition, these lenses are “FF” lenses, so I could use them with a K-1, if I were ever to obtain one.
But, getting back to the question you actually asked, all Pentax bodies with a single digit {K-1, K-3, K-5, and K-7}, plus the KP use a completely different system. In addition, according to research by @photogem; although the problem seems to have resulted from changes made when a sub-supplier moved production to China while simultaneously changing the materials used, Pentax has made several changes in their design, and finally {in the current version of the K-70}, seem to have returned to a reliable system.
