Originally posted by Soligor I have checked it with various other lenses (also with the DA18-55) with the same result.
Maybe I expressed myself unclearly. The shutter is released, thus this is not about AF.
It is the blinking of the three values that is strange to me because
1) It is hard to understand what the "blinking" actually indicates. Is it a "use a tripod" warning or does it mean "now it's too dark to take a shot even with a tripod"?
2) it does not only occur in nighttime situations but also during daytime in certain dark corners indoors (could that be below EV 0?),
3) I encounter it also in M mode, and
4) the phenomenon is nowhere mentioned in the manual, what is mentioned is the blinking of only one of the three values, not all three of them together.

2. All Exposure values flashing, the measured light/exposure is below 0EV and outside the camera's METERING RANGE. (Basically the exposure parameters will change until they light level falls below 0EV, then all items will freeze at the last valid measurement, and flash)
Pentax, when its unable to provide a correct exposure, leaves it up to the user... whilst the values are flashing (whether you find this annoying or not) you are able to still set the exposure manually.
With an f1.4 lens ISO51,200 and manual exposures to 30s you can theoretically take accurate exposures down to -13EV.
I don't think I've seen a hand held ambient light meter that goes below -2EV
When the light is within the 0EV - 22EV the display will flash the item that has reached its limit (ie exposure has hit 30s) then if the value you have taken direct control of, say aperture, can be altered to prevent incorrect exposure the line under f no (Viewfinder) and the pointer (top LCD) will flash. If the aperture can't be opened far enough then the ISO value will flash as being the arbitrary limiting item and either: You'll need to change it to obtain a correct exposure; or (if you have Auto EV compensation set to On) the camera will override this element of the exposure parameters.
You'll have to provide an example of the interiors you want to shoot, they're sounding pretty dungeon like. Oh and don't fall for a lens of f1.4 being better for low light interiors... its depth of field doesn't deepen as light levels fall.
