Ade-oh
Well-known
As I feared then.. Other cameras with mercury batts i had, was easy to fix by turning the ASA to compensate for the higher current, but I've never experienced bouncy needle before.
Was hoping that the OM would be a good camera on the cheap, but with this, I've replaced almost every single component, short of the shutter mechanism.
Scratched matte screen, rotten prism, crumbled light seals, bumpy grip and now a faulty meter..
That's the problem with old cameras: there's a point where I don't think it's worth trying to resurrect them. Even so, an OM-1 in excellent condition wouldn't be hard to find and wouldn't be very expensive either if you wanted to persevere with the system.
