RiceHigh, what you describe was exactly what I though too.
What confused me, though, was the lack of warning - no blinking indicator in the viewfinder when the stop-down metering failed.
If Pentax fixed the stop-down metering warning indicator, I wouldn't have a problem with this.
But its very misleading to have an indication of successful metering with bogus values.
Thank you all.
regards,
Stan

K100D with SMC-M 50mm/1.7.
I know how to work the manual lens, but noticed a weird problem with stop-down metering in low-light conditions.
in "M" mode, I first tried the DA 18-55 lens metering in a room lit by a 100W bulb. I tested f5.6-22 aperture range and the exposure metering came up with speeds from 0.3sec-6.0secs (f22/6.0 secs)
Now, with the M 50/1.7 lens with stop-down metering, I got the following results:
f5.6 - 0.3 secs
f8.0 - 0.7 secs.
f11 to f22 - all get 0.7 secs when stop-down metered.
So, above f8.0, the metering is wrong.
Have you experienced the same problem?
Regards,
Stan
