To get an idea if the meters are even reasonably close, use same type of
lens on both (like a 50), point them at an evenly lit blank wall. Are you
sure the battery in the OM-1 is mercury? They have not been made in years.
If you bought the battery in a store recently and it says 625A or 625U, it
is alkaline 1.55V and throws the meter off as much as 3 stops. So, that
would be a problem right there.
