A om2n I just received from KEH seems to have a problem with the meter. I've compared it to every camera I own, and while all others meter a subject at 125/5.6, the om2n meters the same subject at 30/5.6. The camera is consistent with itself, reading the same way in aperture preferred and manual. I'm using new silver oxide batteries. The thing is, this is the second om2n I've received from KEH, and the first one had the same overexposure problem by about the same +2 margin. Am I doing something wrong? Should I send this one back too? Thanks for your time.
