Metering is unreliable at the limits. Also the camera is probably trying to keep shutter speeds at a manageable level. Meter in live view and see what that comes up with..
Yes, thanks that's a thought - I do realize I am pushing the boundaries and as you say the metering may be unreliable past the limits -
BUT I had just determined it is not quite past the specs - my copy of the K-5 appears to not to be able to reach the lowest limit of LV0 - it get about LV1 to 1.3 - that's over a whole stop difference
- kind of like buying ISO1600 film and finding out it is only ISO800.
Anyway, I do take your point - the reason why I use P mode is probably just due to habit - as I said I have shot this dark jazz club almost on a weekly basis for the past 3 years, and on the K-x I shoot P mode, since I shoot from stage with reasonable light, to off stage - where mostly it is "unreasonable" light.
I bought the K-5 with the expectation that it'd behave in a similar, if not superior, way to the older and lower (entry) level K-x -
it did behave better in lots of ways - but perhaps the most important aspect - the exposure - it did not - the K-x appears for now to work better.
There is now also a very significant input from Ex Finn (posts
#6 &
#12 linked above) as he managed to get 1/4 sec f/3.5 ISO5000 (with 18-55 kit zoom lens, covered/cap on) same firmware (1.13.23.25)
- so why the difference? Pentax K-5 is a precision instrument, but a variation of over 1 stop, not meeting the specs?
I am just trying to determine if there is something I am not aware of, since the K-5 is brand new (to me) - so that I can reach the same in spec lowest metering limit that Ex Finn managed to reach.
I have already determined a workaround - just use the exposure compensation and dial in +1 stop when shooting at the lowest light limit - since that is already in my "workflow" of changing the exposure compensation to suit the scene - this is easily workable for me.

Thanks so much for that input - again it's perhaps habit - on the K-x I shot at ISO5000 max with AutoISO, and not only that, at 10Mp -
so that's why for now I shoot the same settings on the K-5 -
so far the results do look slightly better - except the lowest light shots - the last two dark shots with EXIF and metering segments in the opening post -
but then they were
underexposed by about -1 stop (due to my K-5 not being able to meter to the lowest spec'd limit) - so it is hard to compare to my K-x results.
Thanks for the suggestion -
I continue welcome any suggestions on how to get my brand new K-5 to meter down to the same level as Ex Finn managed (in posts
#6 &
#12 linked above) .
Any other K-5 owners care to please just meter with the lens cap on with the18-55 kit zoom set at 18mm widest setting - @ ISO5000 (with 0 stop exp compensation), please let us know? - only takes a few seconds
Thanks for all the input.
