Mat, I found the same thing with my custom Katz Eye screen (no microprism or split image) for the DS fitted in the K10D: consistent and reliable underexposure with by 0.7EV with the K10D compared to the OEM screen. In the DS model, it produces exactly the same exposure as the DS OEM screen. Autofocus happens in front of the screen so it affects nothing there. The Katz Eye screens with microprism and split image will throw off the Spot metering mode now and then, a little bit dependent upon the lens you're using too IIRC. It has to do with alignment of the metering sensor, the focusing aids and the exit pupil of a particular lens.
