pardon me, but i expect the metering bar working as printed in the handbook page 157 (german edition).
to get the right exposure adjust shutter speed, aperture and iso values so the bar is in the middle / same way as it works since ever.
btw.: light metering has nothing to do with sensor noise, nor with noise reduction.
i'm doing some further tests and will send the camera in for adjustments if it turns out to be a metering problem in other complicated light situations also.

i'm not talking about 'no' light - perhaps about *very* low light.
again:
perhaps i'm just missinterpreting the metering bar in manual mode. i supposed it to work
somehow like on the rollei sl35 i had - if it's in the middle - ok - if it's on the right - too much light, decrease shutter speed or/and increase aperture value.
is the metering bar working different in such *very* low light situations, or is just my camera broken?
edit: if it's the sensor noise affecting the metering - why is that sensor noise not seen in the picture in the meaning of 'exposure' then?

light entering the viewfinder is not the case - happens also in complete dark room.

i just tried to pull down the problem to a reproducable situation.
yes - in very low light situations i suppose at least the manual metering bar to tell me *some* truth. sign of overexposure is not the thing i expected with lens cap on.
without lens cap (supposed usage?) i encounter the same problems in very low light situations - it is of cause possible then to have a "worth" picture by completley ignoring the metering bar and the blinking values - setting everything to something reasonable.
is your k10d acting the same way in such situations? (that was my intentional question)

symptom:
with lens cap on and in manual mode it is possible to have the metering bar competly
on the right side (overexposure) with 3.5 aperture and a 25 seconds exposure time.
putting the exposure time down to 6 seconds, the metering bar is middle (correct exposure?)
exposure and aperture values blinking.
how is that possible? there is no light, the lens cap is on - why does the metering bar can be
on overexposure side, or why are exposure and aperture values blinking with metering
bar in the middle?
