I realise now why. Av mode now works with M and K series lenses by stopping down as you take the photo. Obviously, as the camera has no idea what the aperture is, it cannot tell you the shutter speed in advance. This is a great improvement for K and M series lenses with automatic apertures, but less convenient for preset lenses.
Congratulations on your prize.

Do you notice any lag between pressing the shutter and getting the picture as the camera measures the exposure with a K/M lens ?

Is the "use aperture ring" menu item still there ? If so and you do not enable it, is the behaviour different in Av mode ...ie like the older models wide open only (with shutter speed displayed). If so that may be the best thing to use for a preset or Tak lens ?

I presume if you use M mode (with aperture ring enabled), you get the same functionality as with older cameras when using green button with K and M lenses ?

Must admit I hadn't tried it at the extremes, I'll give it a go.
A quick blow around with the rocket can't hurt either.
Thanks for the input
Mirror up and the AF sensor is in the bottom of the mirror box

Do 10 tests from each extreme to get an accurate assessment.

So the camera isn't finding the same focus point each time meaning any fine focus adjustment isn't final.
That happens with PDAF, although a 50% miss ratio is very poor. 10% is quite normal

Why's this particular camera/lens combination giving differing focus results.
I would give the AF sensor a blow with a rocket blower in case you have dust on it, but its a long shot.

Do you notice how the accuracy compares when you get the lens to focus from infinity versus from closest focus distance ?

Honestly, this is all I am interested in, autofocus and tracking speed.

Every single review I have seen so far says AF speed is not a major concern for them ... ARGHHHH!
Sounds like a trip to Watford is the answer Mike....try it out

Image Sync app on a phone will give equivalent of a flippy screen, and could be more versatile/convenient, and it appears that the latest update can automatically transfer GPS data to the camera.
Although I think the lack of a flippy screen is a mistake for the k3III, I agree with what you say here.

I do most of my photography on a tripod, where a phone linked through the app will be more versatile than a movable screen attached to the camera, and will give the GPS data too.

But there are plenty on forums who do a lot of handheld high/low shots and the phone option won't help them much

Very interesting indeed. A "Zeiss" Hollywood lens, and an early one to boot.

Great find.

You will need to use the camera in M mode for the lens to stop down.

As a user of the K1, with flippy screen, I would just say I do use it a lot. But 95% of the time when the camera is on a tripod, either low or high level.

I cannot remember the last time I took photos handheld above head height or very low down.

Anyone else having this .. Photoshop thro ADOBE Account (So up to date) in use on Mac

Not reviewed PEF fees fo some time as now mainly using " A N Other" Camera
I just went back through my archives and can open .PEF raw files from 2006 with Photoshop/Camera Raw and save as .PSD. I think your problem lies elsewhere.
