I recently bought my first rangefinder, a Minolta Hi-matic 7s, which I'm happy with the first test roll but the light meter doesn't seem trust worthy at all.
I bought a Duracell 625a battery and most of the time the light meter is all the way up past the 5.7 EV factor. It doesn't always stay up there; when I put it directly at the sun, it goes down to about 11 EV. 15 minutes ago I was looking through the viewfinder and noticed that if I flip the camera upside down, the light meter goes all the way down to the bottom 17 EV.
I'm a little confused and wondering if it's the battery type, light meter, or it's supposed to be that way - which doesn't follow the sunny16 rule.
Any information on this would be appreciated. In the meantime, I'll be practicing without a light meter.
ALSO, interestingly enough the automatic setting works well despite the wonky light meter.
