Thank you.
I have just (15 minutes ago) asked them for an offer on a custom screen similar to the one I have in my K20D (Optibrite, custom gridlines, no prism). In the K20D it resulted in about 0.5 stop underexposure compared to exposures with the standard screen, which required some compensation to be dialled in on the K20D. Since the K20D always required some compensation due to the not so consistent metering, this didn't have much impact on the handling of the camera.
The K-7 exposing a tad brighter and more consistently, though sometimes blowing highlights slightly, this should be even less of an issue. I currently am using it in D-Range mode to avoid the slight blowing of the highlights. If the same 0.5 stop underexposure applies, I might just return to normal mode and regain ISO100 without any blowing of the highlights.
Some detail why I'm hoping the KatzEye would work as an implicit D-Range. As far as I understand now, D-Range takes the metering at the set ISO (e.g. ISO200) but the sensor is actually working at 0.5 stop lower ISO during exposure (with ISO200 set that would be ISO140), thus underexposing 0.5 stops and avoiding blowing the highlights.
[EDIT]I just ordered the screen for my K-7.[/EDIT]
I will update this once I have the KatzEye for the K-7 installed.
