If the *camera* is calibrated to 18% then the camera will meter correctly off an
18% grey card; in other words, it'll read the same as the incident meter.
Actually, if you *calibrated* the in-camera metter to a 31.929% grey card (for
example) and took a reading of a 31.929% grey card, you'd get the *same*
exposure yet another different way.
The web page listed in my original post (I have the information at work, I
think) quoted a representetive from Sekonic and Mamiya (same company? same
importer?) as saying Sekonic light meters are calibrated at 12.5% and Mamiya
cameras are calibrated at 14% (and, no, he didn't explain why the difference).
