Catchy, right time shot and add different dimension to the picture.

My last comments on the subject, directed to no one in particular. I will not come back to this thread.
The heat generated by this discussion has grown way out of proportion to the subject. My position is simply that if we knew with certainty what caused the problem, then we would know with certainty how to evaluate solutions, but we do not.
Maybe solenoid replacement lasts longer than the solenoid modification which started this thread. Maybe "white" solenoids last longer than "green" ones. The evidence seems to indicate that at least two years of experience is needed to reach any conclusion - unless some method consistently fails before then - and many K-30/50's won't last that long in any case. Although my usual standard has been to declare any camera which lasts less than four years to be a failure, I find myself strongly pulled towards the K-70, so in the next two years I may replace the K-30 I've now had for just twenty-three months regardless of how well it works.
If you are happy with the solution you have picked, that is great. As long as everyone is aware of the various solutions and picks the one s/he is most comfortable with, then I am happy.

Actually you left out one solution
6. Send K-30/50 to company in California which will "fix" it for $100. We need to list this as a separate option because we don't know what their proprietary solution consists of. Apparently they have had at least one re-occurrence and are "tuning" their solution, whatever that means
and two preventative measures
7. use AA batteries
8. use frequently - don't let it rest for extended periods of time {whatever that means}
I am a mathematician by education and an engineer by trade, so I have evolved to a combination of wanting to know "why" and wanting to see things actually work; thus I believe this discussion needs to remain aware of what we do not know:
A. We do not know what the actual occurrence rate is. The reported overall failure rate for Pentax is around 7%; since that number includes other issues with other cameras, presumably the failure rate with K-30/50 can be only so high. We don't know whether the actual failure rate is 100% or as low as 5% {and a disproportionate number of the failures end up here}.
B. We do not know whether the K-30/50 are especially at risk. Much of the K-01 innards are said to be the same as those of a K-30, and the K-500 closely related to the K-50, but we don't hear much about those two. I know that a number of regulars here at PF use the K-01, so not hearing about it is especially problematic. {Maybe someone needs to sacrifice one to see what is actually inside}
C. We do not know whether the triggering variable is shutter count, aperture changes, calendar time, or some other measure. Considerations (A) and (C) are extremely important, because this thread, which started off with your #3, is just a year old - declaring a method to fail is simple, but without knowing the triggering variable, we don't know when to cautiously say that a method is successful. Similarly, we don't know whether using manual lenses, working the aperture control less, would slow or speed potential development of this problem.
D. We do not know what the underlying cause is. Is the solenoid causing this problem, or is some other part of the system stressing the solenoid.
E. We do not know the difference between solenoids other than a piece of plastic. Perhaps some were made in Japan and some in China, but there is also the possibility that all are made on Taiwan and the change in plastic color is incidental to some other change that occurred at roughly the same time.

Crossposting the text from the "Panorama-orama - Post your Panos" thread but with different images:
Some old school analog panoramas from the Z-1p (a/k/a PZ-1p) film camera in pano mode, taken in 1995 in the central High Atlas, Morocco on Fuji Reala.
When Pentax updated the Z-1 in 1994 they included a "pano mode" restricting the film window to something like 13x36mm. While the Pentax Z-1p served as my main camera from 1995 to 2007, I only ever took one roll of film in pano mode. This was over several days in late autumn of 1995 while I was living in a small Berber/Imazighen village in the Assif Melloul region (also referred to as plateau des lacs in French) in the Moroccan central High Atlas to do ethnographic fieldwork. When my co-researcher (also a Pentax shooter) had to go back to Austria for several weeks due to health problems, I was left with a spare Z-1p body in addition to the Z-1p and LX bodies I was using. So I decided to do a roll of Fuji Reala in pano mode. I took most of the images in the early morning before starting working, many of them with the FA* 200mm. For more images see the flickr album here.

Dang! That was worth the $20 all by itself!
I had a friend with the baby Crown Graphic and it was a sweet package. Sheet film to fit is still available, BTW.

The last one is from a full resolution .fff scan, and shows just how much detail there is in these tiny ( ) negatives!

Found some 120 rolls of Kodak BW400CN and decided to shoot it.
I've always found the magnifier on this camera to be a little worse than some of my other Flexarets, and in the dim light I wound up front focusing. Still, I enjoy the composition:

Well my goodness. If this isn't just about the most wonderful wildlife ever taken, I cannot imagine what is. It is difficult to understand how the hawk could possibly carry one of these animals away. However, I know when I am really hungry, I would do just about anything for a free meal. RAW EVEN! :)
Thanks so much for sharing.

Deer out for a stroll get smaller critters in their path to move sometimes. A Red-Tail can spot that from a long ways away.
The lighting for your shot couldn't get much better.

Nice shot, good colours, but I think I'd cheat on this one and clone out the post next to the table as I find it a bit distracting.

I think this 60 year old 50mm lens is sharper than my pentax lenses.....
Voigtlander Vitessa L / Portra 400 / Tetenal Press kit
The camera seems to overexpose with the built in light meter. All I did to these was levels and bump the contrast. Some of that coquina is razor sharp... on a retina display prior to killing it with compression for the web... also looks like i scanned a hair on the first one.... didn't even see it until I posted.

Oooh ... just back in time for folder talk. :D That's a great method, Mike. I think I'll adopt it entirely! I need to bust out my Franka folders again... it's been a few months since I shot them. Too long.
