The problem, as you point out, is that data is fact and the blue dot supplies approximate data ( try that on next year's IRS return....), the fact in which seems to escape me..... Basically, while I stand corrected, there is no Aperture "data" available to the camera. Frank Filippone red735i@earthlink.net Jerry: Actually, the M8 *is* calculating the aperture. The little blue dot near the M8 logo is a second light meter cell, whose primary purpose is flash exposure calculation. Using this cell, the camera compares the off-the shutter light measurement (which is behind the lens and aperture) with the blue dot (which is out in the open). It can calculate the approximate aperture based on the comparison. Problem is, it's only accurate +/- one stop, so Leica doesn't put it in the regular EXIF data. There's been a bit of speculation on the Leica-Camera-User digital forum that the value might be stored somewhere in the manufacturer's proprietary section of the EXIF. If it is, I'm sure somebody will figure out a way to access it in some EXIF viewer.
