One of the guys on the Pentax Dysfunctional Web Forum chalenged me to test my K20 exposure system with manual aperture lenses (green button manual). The camera failed miserably, over exposing by quite a large amount at all f-stops but maximum and minimum. Would it be possible for some others of us to run the following test:
Put a non A series lens onto their camera doesn't matter which, but it would be nice to have details, and run a series of exposures from maximum aperture to minimum aperture to test the linearity of the metering and perhaps report back. Sorry if this has been discussed before. I ran the test with several lenses, and then put an original equipment istD screen into the K20 as buddy thought that the screen itself was at fault, and insisted that it had been a problem with every DSLR since the istD. The screen was not the problem.
