Chis Simply put, you're wrong. The MR/MR-4 meters DO have such compensated circuitry and so does the SL -- read the literature from Metrawatt and Leica, which is hardly the blatherings of store clerks. Virtually all German photo gear has such circuitry, while Japanese gear does not. (I believe the Rollei 35 also lacks such circuitry, but I'd have to ask Bob Salomon or Harry Fleenor to be certain; in any event, Rollei recommends re-calibration of even the late-production Classic.) I shot for more than a year with PX76 batteries (1.5v silver oxide) in my MR-4 and SL. Both cameras functioned well within 1/6 stop. I am currently using a Kiev prism on my Hassie with four PX76's in place of the original four 625's -- and it, too, is more than accurate enough for chrome work despite the additional 4/5 volt. My Canon F1, however, did NOT do well on silver-oxides: the meter was all over the board and was about 1 1/3 stop off, though this was not consistent enough to be relied upon.
