Never had that issue when shooting OM cameras. I started out with an OM10 and after it broke I got me an OM1. Then I bought the OM2SP which I sold again after a year or so due to the battery consumption. I replaced it with an OM2n and I never missed the spotmetering function. Mostly I carried 3 lenses. 28mm, 50mm and 135mm but I also had the 300mm f/4,5 though it saw little use.
For odd reasons I would like to get an Olympus again but Im put of by the lens prices which, to me at least, seems higher than the compareable nikors though I have seen 180mm f/2,8 that wont break the bank.
Best regards
