Then why arent the A/F/FA lenses using stop Down metering too? Why not, I will tell you Why not again (listen this time ), the benefits Of open aperture metering and AE far outweigh The tiny tolerance error of the aperture Cams and the TOLERANCE ERROR of body controlled Of aperture setting which is probably much Worse than the cam sensor tolerance error Was or will be. Even with critical slide film Or digital. jco

It can't help but be more accurate within the meter's EV range, as it is metering at the taking aperture, not guessing as to whether the mechanical linkage is within tolerance. This may not make a lot of difference, but then again, it might, and digital is pretty exposure sensitive.
