Incorrect aperture value in EXIF

[Kit]

Hey folks! Anybody realised that the camera does not record the correct aperture value in the EXIF data? I'm using the M-P in aperture priority mode. Anybody having the same problem with it or other M bodies? Thanks!

It's not 100% accurate as the camera does not detect the aperture through physical contacts on the lens (like most DSLRs). It estimates the aperture based on the light exposure on the shutter compared to the external light sensor above the lens mount (near Leica logo). Mine is often off by up to 1-2 stops.

Thank you! I read that about the M9 too.
