I still take note of all parameters that don't appear in the EXIF data when using manual lenses: aperture, FL in case of zoom lenses, FL in case I turned off SR with a camera like the K-30 (which doesn't record FL with manual lenses with SR turned off).

More than 350 shots on my Panda during last weekend.
Still going strong and still handling beautifully.

@Doundounba my internal battery has died, so what?
I always sync my camera and smartphone clock anyway before going out shooting, so that all pictures fall in their correct place in the timeline, and I can geotag easily with a GPX file.

Shooting RAW vs DNG

I will continue to use it in all caps as well, as I'm referring to a file category (albeit not a definite file type, such as .DNG) and want to make clear distinction between that and the adjective: "RAW file" vs. "raw file".
Also I find it easier to read, and it's easier to understand at a glance what one means.
And you're right, RAW files are all but raw... one could perhaps say blanched?

Shooting RAW vs DNG

As far as I understood it when I checked, PEFs are (at least on my K-01) uncompressed, while DNGs are losslessly compressed. They both are RAW formats, and the data is the same, as others pointed out.
I chose DNG and never looked back.

The flash does not come out anymore.

I checked again... all the plastic hotshoe covers that I possess (the original ones from K100D Super, K-01 and K-30) have an indentation on the left side, so the metal flap doesn't depress the white tab.
Manually depressing that inhibits the pop-up flash as you correctly diagnosed.

Now the question is: why your cover has no indentation? Third-party one?
In this case, all that's needed is probably to scrape the whole left hand side, save for the first 4-5 mm or so, like this:

...or just buy an original one ;)

That's... unnecessarily complicated.
You still need GPS on and clock sync, and to take double the pictures.
By logging a gpx track you just need one click on your PC.

The truth lies in the middle... GPS works even without cellphone coverage, but A-GPS requires data coverage to download a small packet with current ephemeris.
It was an issue some 10 years ago (and even more recently if you had a Samsung... :p ), since a smartphone needed at least a couple minutes to do a cold fix without assistance, but nowadays we're talking 10-20 seconds without assistance and few seconds with A-GPS, with the worst Chinese cheapo smartphone (of course it varies depending on how much unobstructed sky you have available).

For the record, I log a gpx track and sync with Geosetter as well... If you do that, it's a good idea to sync the clocks of your phone and your camera (also useful if you take pictures with both and want a coherent timeline).

SDM Deactivation - a Theory as to why you can't do so on newer bodies.

My K100Ds no longer works even with fully charged Ni-Mh... it has never been used to do a SDM conversion by me (though I don't know about the previous owner). It has been fine for quite some time (2.5 years of good use) while in my possession.
It started to go bad when not used regularly (i.e. when I bought a K-01). Given it's an old-ish camera maybe it has been the same for you as well i.e. not used much anymore and then developing quirks?

Gut feeling only, I don't think the two things are related.

Pentax K-01 - Flash won't come on -
If all this doesn't help, given that the camera needs to be on (unlike, for instance, the K-30, where it's just a catch and a spring) it's probably a failed electromagnet.

K100D eating through batteries

Did you test the batteries with a multimeter?
I used to power my K100DS with Ni-Mh rechargeable batteries, but after some years it started signaling empty battery even when inserting a fresh set.
Of course the batteries still read good after removing them from the camera, and could power a flash, so they were not the issue at all.
Alkalines forget about it... in a cold climate they didn't work even when the camera was ok with the Ni-Mh.

If by "the aperture problem" you mean the same issue that plagues K-30, K-50 etc. (that is, a defective solenoid) then there are countless tutorials online, even on this forum.
If the camera is a write-off anyway, I'd try opening it, see if one can use the same procedure or adapt it somehow.

Edit: I checked, and it looks like it's a different issue altogether. Apologies.

Use of UV filters to reduce purple fringing?
Posted By LensBeginner
Replies: 23

I tried this some time ago on a SMC-M 80-200/4.5 1st version, and I'm afraid the potentially detrimental effects are one and the same with PF reduction.
That lens is prone to PF on high-contrast edges, and it goes hand in hand with its high resolving power.
Now, the fact is that different wavelengths focus at different distances, and, before ED glass, one could focus 2 primary colors out of 3, but never all three at the same time, hence the fringing.
UV filters just muddle the image, kill resolving power and PF with it.
So, yes, one can use an UV filter to reduce PF, but the price to pay is too much IMHO, and has nothing to do with cutting certain wavelengths, which is what one might be tempted to infer at first glance.

There also is the off chance that they interpreted your posting 79 pictures as hybris, I mean, not like "Here are my best pictures for the year: too lazy to select my best 4", but like "Here are the pictures, I have 79 best pictures because I'm much better at it than you lot, thus I deserve more space and attention".

It's easy to misinterpret someone's intentions on the internet, because of the lack of non-verbal clues among other things, especially if you don't know the other person.

You should post a picture you took, either one you're not satisfied with or one you think is close to your intended target but not quite there yet, and then we can probably tell you where there's margin to improve the end result.

That camera has no IR cut filter; astrotracer is good but has its limits.
Using that camera with a motorized mount will probably yield better results than a "normal", all-purpose camera.
So, I really don't see anything to LoL about.

Best manual focus 50-ish mm lens at around f/8 or f/11
Posted By LensBeginner
Replies: 40

Based on my tests on a SMC-M 50/1.7 on a couple of Pentax 16MP bodies, I've found the sharpest aperture to be f/5.6, f/8 being a whiff softer (probably due to diffraction).
I didn't test it on a FF body, so border/corner performance could be different (on APS-C it's sharp all over the frame at f/5.6), but, due to pixel density being the same between a 16MP APS-C body and Pentax FF models, degradation due to diffraction should be identical.

As already stated by others, performance at f/8 is largely meaningless in order to evaluate a normal lens.

I enjoy them on a profiled TV.
I often go back and look at pictures from past trips/promenades, but even more relevant, I harness the power of keywords in order to find smartphone pictures I took of some DIY, some odd job at home, a dish I prepared in a certain way... or "proper" camera pictures inside museums, especially if I happen to see another work from the same author after some time.
