Valuable reportage picture; man and his animals in a fairly barren landscape; also fine colors

Around 1990 this part of a shut down paper mill was transformed to be headquarters of the IT company Telia. The great dome was added and the pool constructed atop a parking garage.

A lens for special purposes. Mine is for the APS format.
It is invaluable for rainbows, haloes and other ultra-wide sights. A double rainbow (102 degrees in diameter) fits comfortably in the APS format. It shows off-center round shapes with less deformations than other ultra-wide lenses. Off-center straight lines are bent and so need special care when composing a picture.
It is good for interior shots in cramped spaces and occasionally for special effects.
The new version of this lens can be used on a FF camera like the Pentax K1.

Hello and welcome! I took the step to K-1 at the New Year 2020 and find the camera just great.
For your need, I can really recommend the SMC Pentax-FA 1:2 35 mm. One sits on my K-1 most of the time. I got it in fine shape at Tradera for about 1200 Swedish krona including the original sun shade, an item worth using.
This is the elder sister of the Plastic Fantastic Pentax DA 35 mm f 2,4 AL lens. I picked one up for 400 Sw Krona. It is extremely light and works perfectly well on the K-1. Stopped down to F 11 it shows no vignetting but there is some at fuller apertures. And it does not come with a sun shade as standard.

Very interesting!
1. I had no idea that the K-1 offers a colour invert function! I checked and it works even in Raw. I have not used it for negatives yet but if it works OK it would be great. Negatives are really hard to digitize.
2. The Pentax Bellows and Slide Copier from the 1970´s is beautifully made and a joy to use. The K-1 did not fit, but I trimmed away some metal and now it works just fine. See review here on Pentaxforums.

Very good information here! Helped me a lot.
I have two lenses, Meyer Optik Orestor 135 mm and Meyer Optik Orestegor 200. They share the same M42 mount. When used on my K3 II with an original Pentax adaptor the performance was downright disappointing. Both mechanically, the coupling was wobbly, and optically.
The cause: These lenses have such a narrow base that they do not mate to the Pentax K camera houses properly, just hang on the adaptor.
After reading this thread I cobbled together a kitchen-table solution. I made an epoxy fillet on the original M42 mount. This fillet extends the diameter just right so that the lens sits against the camera body.
First step: Make a template that guarantees that the mating surface is flat and exactly aligns with the original mount. I cut out a 42 mm hole in a flat plastic lid from a food container. Make sure that the plastic is of a type that epoxy glue does not bind to. Then i cut out the required outer diameter. Then I fixed this ring-shaped template onto the M42 mount using the Pentax adapter. Then I protected the adapter and most of the mount with adhesive tape.
Second step: I built a fillet between that template and the M42 mount. I used quick-setting epoxy glue with a filler of powdered chalk that I happened to have at hand. I applied it in three or four steps using a a wooden match as a tool. After hardening overnight I removed the template and trimmed away the surplus epoxy. I painted the fillet black to stop light leaks. The surface mating to the camera was left unpainted. It is perfectly flat and glossy.
(Caution: do not get epoxy on your hands or anything else.)
This worked lika a charm. The lens now sits firmly on the camera. No wobbling. No light leaks. And the Orestor/ Orestegor perform very well.
If there is any interest I can add photos to show details.

The island of Gotland in the Baltic Sea holds its landscapes and history in high regard. Here you see a 3000 year old stone setting, a burial monument for an important chief in the Bronze Age. Geese call from the shore. In the distance you see a small island, an important bird sanctuary.

Every step in this cylindrical staircase is hewn from massive oak. It was built in the seventeen hundreds and serves a medieval building in the city of Lund, Sweden.

Many fine "weather" images". Hard to choose.
However, several submissions have signatures. I think contest like this should keep signatures away.
