Nice and sharp. Never heard of that f3.2 lens. :P
On a serios note, love the shadows and all those details.
Have you tried it for astrophotography with the appropriate filters?

Quick snapshot of my Z-1p's viwefinder:
The crop lines are there. Your camera must have a replacement screen. Does it have a split prism, perhaps for manual lenses? As you can see, the original has a center circle marking the center weighted exposure setting and brackets for the AF spots (3 I think if I'm not mistaken).

Yes! It's one of the good links that popped up upon searching for the camera. Very detailed info on that page. I also found a channel on YT with a series of videos on how to CLA them. I learned quite a bit and it's gonna come in handy once I commit to the task one day of servicing a bunch of shutters from large format lenses I inherited.

^^^What he wrote.
Those orange/yellow markers seem to be for actual aperture after light loss, rather than working aperture. When the lens fully extends, it seems to lose two stops of light. This makes calculating your exposure easier.

Lovely sunstar, morning haze and harvester shots, guys!
Because it's a good lubricant AND conductive.
The best option would be a dedicated graphite powder or suspension, but a #2 pencil will do the trick.

I've seen a lot of Russian projector lenses being adapted to medium format. But that's a rather deep rabbit hole to dive into.

Beautiful view of the Elbe! My dad's friend used to work for Elbe Schleifsteine. I'll have to make that hike someday.

Love the grain bins with the sunstar.
As for your issue, make sure your battery contacts are not dirty/corroded by air (oxygen), time and use. Cleaning them with isopropyl alcohol and a swab can help. Some graphite from a pencil afterwards is useful, too. Just brush off any excess.
My K-5 started acting up and this eliminated the problem. Old batteries can be a source of inconveniences, too.

That's completely true. Although for the P67 system there's no bad lens choice, since most perform exceptionally. With the same lens, one could get the same results with an ugly, beat up first generation 6×7 as with with the latest 67 II.
As for today's systems, many kit lenses are just rubbish. If they weren't, people wouldn't buy anything else. Even then most people don't. And for family photos, that's okay. It's more about the memories and stories behind, than about the picture quality itself. And no Photoshop needed with softer lenses. [emoji23]

I suspect this could also be an IR hot spot. Given the long exposure and red-shifted light coming from a setting sun. Also, with these longer exposures one has to cover the viewfinder because IR tends to enter through it and color cast/smear all over the image.
I would keep a small circular cap that fits over the eyecup in case there is a chance that light can enter. People also use gaffer's tape, but I'm not sure how effective it can be against IR.

My experience is a bit different. I live in the outskirts of a big city, and most street lights are sodium vapor, but in the last eight years, the lights everywhere else (houses, yards, fields, buildings, access roads and gates, etc.) have become brighter and whiter. Even though it lies in a valley, you can see the dome of light shining out of it from miles away. It's a bummer, but it's also very difficult to do astrophotography here because of the climate conditions.
I do fear the day when all these lights will outshine even the full moon since there are no regulations about spill.

I had the same problem. It's just a matter of applying a tiny amount of thread locker and tightening the screws. Problem solved.

I think that you're asking too much of just one lens. Most lenses are corrected for infinity and perform accordingly worse the closer you get, unless they have very complex focusing mechanisms with "floating elements" or group focusing. Zeiss lenses are certainly built that way and is the reason why the K 28/2 also performs so well at all distances. Most lenses just focus by moving the whole optical assembly away from the film/sensor plane. The Irix has rear group focusing, which is excellent for weather sealing, since less external parts are moving relative to each other which could promote water transport through those surfaces, which I think is great, because many great lenses aren't weather sealed, and in this case I don't have to worry about it getting wet under the rain on some hike, except for the water beads that get in the way of the picture.
All lenses have pros and cons, and I think this one's got a lot of pros.
+ Weather sealed
+ f/2.4 for anything indoors and after dark.
+ Focus lock, infinity adjustment, infinity stop with ability to go beyond in extreme temperature cases where focus shifts.
+ Ability to use filters
- Weight perhaps since I have the Blackstone version, but it's f/2.4 and not f/4, so… maybe Pentax should have a 15-30/4 with filter ring.
- Manual focus, but that can be a waste, too from what I've learned from my experience with the smc DA 15/4 (which also isn't WR) since I have to focus it on the corners in live view because of its strong field curvature.
So, and as far as macro lenses go, thay are corrected to perform best at certain magnifications. Perhaps just 1:3 to 3:1 or 1:inf to 1:1 and you have to turn them around to use them for greater than 1:1 magnifications. That being said, I think you should try out the Laowa 15/4 macro. Maybe it's a good middle ground and great to use for architecture on your K-3ii.
I would also suggest you show us with pictures what you're exactly talking about. Is it perhaps the chromatic aberrations at close distances? Can they be fixed in pp software? I think most of it should be able to be corrected.
One last thing, I warn you, that although it's a UWA lens, it's depth of field at close distances is way thinner than you might think, and things in the viewfinder look too small as to discern correct focus, so a tripod (not just a monopod) and absolutely still subjects are essential.
For less than still subjects there's always the option of continuously shooting while slowly turning the focus ring.
Remember to post some pictures so we can get a better idea of what bothers you.
