I'm hoping someone can assist me in determining what is causing my OM1n's meter to be indicating a very low light level when in fact I am testing it at noon on sunny days here in lower New York State. With lens wide open and 400iso film I need to shoot at 1/15th or so to have the meter indicate a "proper" exposure. At first I assumed a dead px625 Weincell and have replaced twice to no noticeable effect. I source my Weincells from B&H and would hope they're fully charged upon receiving them. I've cleaned the battery contacts but again no luck. I always remove the cell's protective strips at least an hour beforehand. Meter worked perfectly this past spring. Although I have an F100, an A1 and AE-1 program this is my first camera of choice, I love the damn thing! Please Help!
