Jens, I think I exercised it 1000 times. Didn't make a difference. Off to
Pentax Sweden with the M28/2.8 and yes, they could fix it for 788 SEK,
that's about 110 USD. I think you could have one on ebay for less. the
question is however, how prone old M-lenses are for this kind of disease. I
have at
a while, anyway :-)

I agree that you have a couple of lenses which need a cleaning.

Perhaps you have sticking aperture blades, and they don't stop down
sufficiently. I experienced that problem in the studio with flash lighting and
a sticky lens.

Jens,
its only two of the lenses that behave that way (M28 and M50/1.4). The
other work just fine.

Nope!
All my old lenses work just fine (A20, A28, M35, M1.7/50, K105, K135,
M4/200, M*300) - even my two Tamron Adaptall lenses work fine).
A possible explanation could be that old Pentax "slow aperture syndrom" -
the lenses stop down to slowly - if the have not been used for a long tim or
been sit
Maube, but why don't I have this problem with all the lenses, then?

Could it be because with K and M lenses you get center weighted

The test scene is outside, buildings, the sky and few shadows. It really
should be the other way around, i.e. slightly underexposed due to the
relatively bright sky.

What are you metering? If your scene includes a lot of shadow area and
no sky, you'll probably overexpose somewhat.

Can't help with an explanation but can attest to the same experience
w/ M 50/1.7 and 28/2.8. I just go for a solid under-exposure and it
turns out well, but then again I do not plan on using them again as I
now go auto-focus. (If anyone wants the above two lenses for AUD130
