Pattern continued today - one dark one, followed by roughly a dozen good ones.
Ten hours after attempts reported earlier - one dark one {not black one .... even on camera screen I can vaguely see that something is there} followed by two good ones. Apparently mechanism is tightening up in fairly short time, but it takes only one to free it up for awhile.

have you cleaned your lens and mount contacts and made sure they are not gunked up? Your intermittent issues sound like they could have other causes. Stevebrot is the forum member who is best at diagnosis via forum chat so i would PM him.
The problem persisted after I had the camera professionally cleaned, and it doesn't matter which lens I use. Once I start stopping down the aperture, everything goes bonkers and the communication between the aperture and the shutter goes out the window. The estimate I got for repair was $250, so it got booted to backup for my K3 and I just use the K50 to shoot wide open or in very controlled situations that allow me the time to dial in all the settings. One thing I never did check was for firmware updates.

250$ is too much, repair should be 100-150$
Firmware updates don't solve the issue.
You could get a link from one of those who repaired it cheaply in this forum, can't recall who they are presently though...

Correct, that's why I didn't pay it- that was quoted from Precision Camera BTW. I did see the Pentax repair site you are referring to, and they are still charging $100, but that is exclusively for the aperture block problem, and I'm not 100% certain that is the proper repair. I have an excellent local camera shop, but they are of course clueless on Pentax as they haven't carried them in 15 years. Colorado lost it's last Pentax shop 2 years ago, right before Ricoh moved Pentax operations from here.

Bummer... that's not an easy decision then...
Did Precision say exactly what they were goinf to fix in their quote, or it was just the price?

Not sure- it was an over the phone thing when i described the symptoms, so it was an estimate. At the time, I could buy a new one for around $300 as it was just before they were discontinued, so I assumed they didn't know what was actually wrong and just figured on swapping all guys into my body to make it a refurb camera!

I am fairly sure it is not the proper repair - however, I believe that site in California does other repair work. It might make sense for you to contact them and see what they say, whether they think this is the $100 problem or whether they have other ideas.

As I recall it says on the site he does not do any other repairs. If there are other faults other than the aperture stop down setting failure you need to go elsewhere..

It's certainly been reported with the K-S2, Gatorguy.

The issue seems to be that solenoid used in the low end models. It can be not up to spec.
Well then...
Maybe I should keep an eye on both for any signs of a problem. Thanks, was not aware of any verified ones. Lucky for me Adam is sending a K-1 my way tomorrow.

There is a stop gap measure i dont think has been mentioned. You can hold the aperture open. I tested this by wedging some twist tie in the slot to hold the aperture open. Not precise but better than f22. My use was macro on manual tubes but ot worked

You are correct. Given the cost estimates and that I don't shoot many moving objects, it still works as a good backup in manual mode.
