There exists an A 35-70/1:4.
Not sure what's available for medium formate.

I think this information is wrong.
The hyperfocal distance depends on how you define the circle of confusion and is very subjective. I very much doubt that Pentax would integrate such a thing and have never heard it before.

Perhaps it's not waiting for the blades to shut down before metering? (Which would explain why smaller apertures cause more problems as it takes longer to get to that position.)
No, this is not the reason.
You can meter using the optical preview and getting the same errors.

Yes, given that it works OK with all lenses when set to A, that suggests it is not a focussing screen problem but a software problem.
That does not logically follow.
The metering works ok basically up to f4.
And basically all lenses are in this range in A mode (f1.4 - f4).

Only above f4, expec. above f5.6 the metering performs wrongly.

It is possible that they used the program code from the istDs for the metering, but the K10 has a different screen and needs a different assignment table or so. Then it could be fixed with the firmware.

1. The error has to do with the screen.
It has been repeatedly shown that the error does not occur anymore when using an istDs screen.

2. Pentax does not seem to be much interested in the problem. I mentioned it to Pentax Germany and they said "well this may occur, these are sooo old lenses etc. and we have more important things to do, stop lamenting ...".

It is sad, but I don't have much hope that Pentax will fix this error in the K10.
Perhaps, hopefully, in a future body! Better still a stop-down coupler in the body!

When the windows viewer looks over-saturated I think it is the screen profile.
Right-click on the empty screen, properties, advanced, color or something like that. Select the correct monitor profile.
