Originally posted by tripodquest I don't upload the pictures from my camera every day or even every other day so I don't like the idea of having to do that every time I have a problem. It would help me if you could tell me what you are looking for in the EXIFs. Is it something I can see in-camera? (probably not?) The lighting doesn't mean anything since before the problem came up, I took two pictures, one with the flash in the 5th dimension on the planet Fluffluvian (just so it's clear it wasn't in the picture in any sense of the word), and one with the flash on as a light/fill light/whatever. The exposures and settings in both pictures are the same, and all the flash did was make the colors look better and add a tiny bit more exposure to the leaf, that's all. The only way the lighting was the issue is if the action of putting something metallic in contact with the hotshoe plate in the camera causes the camera to reduce the exposure by 10 stops.
I just want to see the images, I want to see the inconsistencies and have some information to back it up. It is starting to sound like you aren't having exposure inconsistencies with the camera, though it is hard to pick out relevant information in your posts without some images to back up your words.

If you did the test with the DOF preview lever, like I mentioned earlier, it should rule this out. I just asked for a yes or no to "does the viewfinder get darker and brighter as it should". You seemed happy with the results from this test, though I have no idea what the relevance of the meter was, so I just left it alone.
Also, if the camera is able to open the aperture, then you have a native K mount lens. The other lever you see recessed into the mount is for communicating aperture ring position to film cameras for the meter, it is not used on a DSLR. Pictures of this lens would help too, of course.
