Alas, I already tried that, and have updated the firmware too. Neither made a difference.

Sounds like a good idea.
Hmm, but the only other person I know with a modern Pentax is away on holiday for a few weeks the inconsiderate bam! He should have foreseen my needs and cancelled it! Lol
Wonder if I could be cheeky enough to mosey down to the camera shop and 'test' an AF lens ;)

Hmm, I've only got 70's M glass for the Pentax at the minute. (Been keeping my beady eye out for a 30mm 2.8 K too :) )
Thus far I've put a couple of hundred shots through in manual and other than the aforementioned infuriating metering issue she hasn't missed a beat. I'll need to see if I can rustle up an AF from somewhere to try.

Thanks for the replies.
Aye, I'm in manual (M) mode. (I do actually say that twice above! ;)
So what I'm doing currently is:- set the aperture using ring on the lens, focus, compose, then press green button, the camera then stops down, has a look and in live view meters correctly and sets correct exposure time. I then press the shutter to take the shot with the suggested exposure time.
But if I do the exact same thing using the viewfinder, it stops down, has a look, meters incorrectly and sets a stupidly short exposure time.
ISO is fixed in all cases. No auto ISO is set.
And metering is set at centre weighted, definitely not spot, and as vonBaloney states Matrix metering isn't available in M mode using manual lenses on the K-R.
On the two comparison shots the ONLY difference is whether the stop down metering was done in liveview or viewfinder.
It's a real PITA! lol

Hi Guys
I've an old SLR that came with a few of the old bayonet mount M series lenses, so I got myself a K-R to slap them on.
Now they fit fine, but I'm having a problem with the metering in manual mode in the k-r when using the viewfinder.
Basically, when I try to use stop down metering, the exposure time, and exposure reading are massively off - as if the camera seems to think the environment is WAY brighter than it is - so it will set stupidly fast shutter speeds. So black pictures ahoy.
BUT, when I switch to liveview and do stop down metering it works perfectly! Problem is I hate using liveview to frame shots and it's a massive pain in the hole to keep switching back and forth.
So does anyone have any idea what is going on here? Am I the only one experiencing this behaviour?
First a few answers to the obvious things folks will suggest:
1. I have set Use Aperture Ring to PERMITTED
2. I have entered the focal length when prompted upon turning on in M mode.
3. I have set the green button to Tv Shift. (Also used the av+/- and same issue)
4. I have tried both the lithium battery, fully charged, and brand new fully charged AA's. No difference.
5. Contacts are clean as can possibly be as I have cleaned them a few times now to be sure.
6. Lenses in question all have metal mountings and are also clean as a whistle.
7. Aperture blades are in perfect condition and aperture lever on lenses work perfectly.
8. If I change the aperture setting on the lens the camera correctly stops to whatever I've set when taking a picture ( glared down lens with torch at every f-stop to be sure). Optical preview also works perfectly.
9. When I try metering through viewfinder eye is up against it and I've tried covering it completely... no difference.
Like I said, I can live with using the liveview for metering (grudgingly) or just good old fashioned sunny 16, but it'd be more convenient if my exposure meter worked properly through the viewfinder.
So all that being said... does anyone have any idea what's causing this?

Cheers in advance
