Not something I see often:

UNIKAT! Canon FD 4,5 500mm L MF - Umgebaut auf Pentax-KA Bajonett ! | eBay
UNIKAT! Canon FD 2,8 400mm L MF - Umgebaut auf Pentax-KA Bajonett ! | eBay

500mm F/4.5 and 400mm F/2.8 Canon FD lenses with mounts (and whole aperture assemblies?) swapped to Pentax KA.

I have no affiliation with the seller.

Are we conditioned to spend ?

Interesting thread. A few random thoughts...

Conditioned to Spend?

Reminds me of a leadership course I took, in which we explored Maslow's Hierarchy of Needs, which he introduced in his 1943 paper, A Theory of Human Motivation.

1. Physiological needs: air, food, water, shelter, sleep
2. Safety needs: personal security, health
3. Love and belonging: friendship, community, connection
4. Esteem: respect, recognition, prestige
5. Self-actualization: desire and ability to achieve one's full potential, become the best that one can be.

The most basic needs -- physiological and safety -- are inherent in humans. The others may be important or not, depending on individuals. In our capitalist, currency-based society, spending (money) is necessary to achieve the basic needs. I suppose one could avoid spending by foraging for food and drinking from a clean stream, but these solutions are hardly practical for most humans.

Consumerism?
Occasionally, I may receive a gift card to Starbucks Coffee. I'm quite amazed by the high prices of their products -- especially when compared to my mid-morning home-made 25-cent coffee and 15-cent muffin -- and even more so by the long queues and busy cafe, which seems populated mainly by young patrons. How do they afford $10 for a frequent drink and snack?

IMO, yes, we're inundated with invitations to spend. That's what advertising is all about. Then there are the slightly-less in-your-face subliminal pitches -- you NEED this 20 FPS, gnat-AF camera... how could you possibly take good pictures with your old piece of gear-driven gear that's five years old? Fear of Missing Out?

We can live without
I'm reminded of a Pentax Forum post of a few years ago:

Mend and Make-do

Likewise. My engineering education served me well, financially and with interesting projects. I never became rich in the Canadian government public service, but our family had comfort.

I'll usually try to make or mend things around the house -- minor plumbing and electrical jobs that don't require permits, woodwork, mortar, appliances (minor and white goods), etc. Saves a ton of money. Glad to have my basement workshop. And, our quality sewing machine was one of the best items we bought after we got married.

OT
Finally, about the BBC. I often depend on BBC online (or CNN) for coverage of unfolding world events. Our own Canadian Broadcasting Corp (CBC) radio is pretty good for documentaries, music, and current affairs.

Enough for now. I'm off to check the Shipping Forecast for the conditions in Dogger. ;):) Seriously, though, there's something to be said for the longevity, consistency, and calm of the Shipping Forecast, in the age of consumerism.

In 2017, I was able to drive to Idaho from Washington and shot the eclipse with my Pentax fish eye lens (time lapse) and the DA 560 at totality.

In 2024, I had to fly to get to the path of totality. MFT was the way to go with OM-1 bodies and 12-40 and 150-400 TC more easily packed for travel.

Here are shots from Carbondale, IL. Time lapse with the 12-40 up to totality and quick shots with the 150-400 at totality. The experience made special by a northern cardinal singing it's evening chorus as the light faded and temperature cooled just before totality.

Sharpness of HD Pentax-DA 15mm F4 ED AL Limited

Not much to add here, but as your cat is in 'panorama', how did you crop the pic?
I have the SMC version and for traveling I just love the 15/18-135 combo. As others have stated, backlit pictures are a strong point, also in landscapes.
I also found one 'architectural' pic in my collection. Both at f8......

As already mentioned, the DA15 exhibits quite pronounced field curvature - as shown by this field map from DXOMARK (measured at f/4 - i.e. wide open):

The situation improves as the lens is stopped down through f/8, but the borders will always fall well behind the centre for flat-field subjects...

Having said that, the right hand side of your example shot does look particularly blurry, and I wonder if it may be decentered. More testing is required, I think, with flat subjects that fill the frame completely...

I looked at my own shots on Flickr. Most are at f8 or f10. And when the subject is “flatter” they seem ok.

The K3 would be the better bet unless you can be sure the K5 you are getting is a later run. The early K5s were rather plagued with a variety of problems and you don't know what you are getting until it's too late.

Some idiotic decisions by yours truly:

- A friend got married. Yup, they asked me, yup, I did it. But with the usual disclaimers, I'm an amateur, I just document what I see,...
- I decided to go with two different cameras. K-1 with HD FA 31, K-3 III with DFA* 50. A wide and a slight tele. I don't have a harness, I just used the neck straps and let one of them hang on my body while I shot with the other. Worked out okay, the strap on my K-1 was a little shorter so after a while I decided to switch it so that the K-1 was on top. One thing that did happen: I didn't switch them off when not using them, so at more than one point my settings got changed by accident. Noticed not immediately, but rather quickly. Shutter speed and aperture changed led to a few more or less ruined images, while a change in White Balance could be easily corrected afterwards.
- Another thing I hadn't fully thought through before starting the day with two cameras: I hadn't synchronized their clocks to the second. When I had culled and edited everything, I wanted to sort them by time and assign them a sequential number, and that's when I realized that something was not right. I managed to adjust the difference with the help of EXIFToolGUI so now it should be very close to the correct course of events, and trying to solve this made me learn some things in the process, but I could've lived without the experience :D
- I shot a lot. 1300 clicks? I delivered 442. Culling was gruesome. Ceremony at the town hall, congratulations and a little celebration by friends afterwards, small detour with just the newlyweds to a location for some staged shots (some rain, cloudy, coldish, so not the greatest), and some group portraits with the closest family.
- I only realized I hadn't matched the WB between the two cameras after I had fixed the time issue, at that point I wasn't willing to fix the WB if my friend didn't mind.
- I didn't chimp for most of the day. Which was absolutely necessary or I would have missed so much, but it would have prevented a few shots with horribly missed focus. I went with a small zone and AF-S, which worked out okay for most of the shots.
- I did it for free. Or as my gift to the couple. They offered to invite me for dinner which I will accept when we find the time. But still, it was quite a lot of work.

Well, after all I learned a lot (most importantly: don't do it again? :D), and I hope I will remember some of the issues that showed up. And perhaps when you read this you can find a thing you would have done differently? One thing I will probably change in the future: get myself a 16-50 PLM and shoot with that on the K-3 III only. The K-1 files are very nice to work with (for example I completely misjugded the exposure in a scene so that the bride's dress was completely blown out, but I could recover it in most of the shots), but the buffer fills quickly and clears slowly.
