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?
