Re: K10D and Lenses with Aperture Ring
If you move the camera at all after the metering has been set with the AE-Lock button, the EV value will reflect the difference between what is now in the meter's sight and what was metered on. It's quite sensitive. I often find it is off by .2 to .7 EV in either direction because I don't have the subject centered exactly the same way. But it is definitely setting the null point.

I forgot to add ... use an out of focus white wall as a test target.

Re: K10D and Lenses with Aperture Ring
I suspect that's because you are moving the camera in between the two events. Try it with the camera on a tripod, pointed at something with a constant level of illumination.

Re: K10D and Lenses with Aperture Ring
It won't be set to 0.0, remember the meter will still be on and will still be giving you a reading without aperture information. However the shutter speed will now be set to give you the proper exposure, if you're not outside the acceptable metering range.

Re: K10D and Lenses with Aperture Ring
The lighting may have changed slightly between the time you pressed the button and the time you use the DOF for a reading. Another possibility is that your lenses aperture blades are slow. This will give you a shutter speed higher than expected as the lens will not be entirely stopped down when the reading is made.
