I just got an OM1n to supplement my beloved OM2n and I'm a bit disappointed at the viewfinder. On my OM2n, the Zuiko 50mm lenses perfectly match the viewfinder magnification to real-world dimensions so that looking through the camera is almost like looking through a rangefinder window in that the image in the viewfinder is life-size. The OM1n, however, has the same size magnification but the viewfinder suffers from a parallax error so that the image I see through the viewfinder is offset compared to the real world. I'm wondering if all OM1s are like this or if mine is somehow knocked out of whack. I'm really loving the OM1n because it works without batteries but the viewfinder is sort of bumming me out. The OM2n has the best SLR viewfinder I've ever personally seen.
