I just got a really nice Voigtlander Vitoret 110EL for super cheap but the roll of film I ran through it (from Frugal Photographer so not ancient dated stuff) badly overexposed all shots regardless of setting. It has two new LR44/A76 battery equivalents and appears to be working otherwise as the light in the viewfinder responds properly. Is this possibly a battery problem—too much or too little current in the modern replacement for the meter to read accurately? Or am I screwed and the camera isn't going to ever work properly? Thanks!
