This would be specifically interesting for a fast lens, perhaps an F1.4 50mm and an F2.8 zoom, as well as the relitively slow kit lenses.

I know the issues with metering on teh K10D very well, and have tracked this down to the focusing screen, combined with a software fix for A lenses, that actually makes manual apature lens metering an interesting experience, and am really intertested in how the screen performance with K10D metering really plays out.

Can't help you with K10D, but if you are at all interested in K20D results, and my patience permitting, i could do whatever test you want using my Nokton 58/1.4, may be also educational for me to know how much it changes and determine what (if any) EC to dial in.

Mine won't be a Katzeye, but one from jinfinance, which is laser cut from a K1000 split image screen.
Let me know if this helps anything.
