When I last used my ME S I noticed that, while the shutter speed indicator lights in the viewfinder were working, they didn't match my judgement of what the correct exposure should be. Speeds were off by a couple - three stops at times, other times they seemed closer to accurate.
Today I ran a quick test, and compared the exposure readings to that of another camera with a similar metering pattern, and determined that the ME S readings were, indeed, off in some circumstances. I then installed some fresh batteries and compared the readings again. With the new batteries the readings were accurate. I've never encountered this exact problem before. Will a battery that is low on power, in this case a lithium cell, cause such problems, or might there be another factor involved? If such is the case, here's another argument against relying too much on the built in meter of the camera and electronics. Had I not been paying attention to the shutter speed readout, as one may easily do when shooting aperture priority with an automatic camera, and not trusted my own experience as to what the proper exposure should have been, there'd be a lot of poorly exposed frames on that roll of film.
