I love my Olympus OM1n camera, it is my forever 35mm SLR and I have shot with it long enough to know this true. The other thing that I know to be true is that Olympus Zuiko lenses are fantastic and completely underrated by those that do not know. I currently own the 50mm f/1.8 which was the ‘stock’ lens that came with the camera and the 28mm f2.8 which is one of the best around in my opinion. So as you can see I have wide and standard covered but what about longer focal length? I did own the Zuiko 135mm but I found it heavy and it made the camera feel unbalanced in my hands. Thus I started the quest to find something that worked for me. At this point I should mention I am not a portrait shooter, thus I discounted the Zuiko 85mm f/2 and started my coveting of the Zuiko 100mm f/2.8.
