Hi, I am a novice photographer, learning the game with a ZX-M (MZ-M in Europe, I believe) behind a SMC-A 50/2 lens (I own no other equipment whatsoever, though I intend to get a tripod and maybe a flash).
The manual says it does 'Multi (2)-segment metering' if the lens has an information contact (KA and subsequent mounts) but reverts to 'Center-weighted metering' for K mount lenses (SMC, SMC-M). Further, Center-weighted metering results in 1-stop overexposure and hence the user should compensate (or leave the aperture ring on A). Two questions: one, what is 2-segment metering? Does anyone know which areas in the viewfinder comprise the segments, or is there an easy way to find out? Are the two segments weighted equally or differently when calculating the (average) exposure? Second, I can't figure out why center-weighting results in 1-stop overexposure. Could someone illuminate me? Some more questions: the camera can't pass information to a K mount lens, hence Tv and P modes don't work. Then how would setting the aperture at A work? The camera (presumably) can't stop the aperture down as required. Finally, how does flash metering work in the ZX-M? I am totally ignorant about using flashes: how do I set exposure when using a flash? Can I use a Pentax flash (say AF220T) as a fill flash? Thanks, Badri
