My name is Bill and I have too many cameras. My 35mm system is Olympus OM and I do own or have owned almost all the Zuiko lenses for these cameras with the exception of the "Big Whites." One lens that has passed through my kit a number of times is the 40mm f2, however I never held on to it as it always seemed way too many dollars for relatively little difference between the 35mm or perhaps the 50mm Zuikos. I just couldn't fall into the infatuation some had for "pancake" lenses. So fast forward a few years from the last time a 40mm f2 Zuiko lived in my stable. I recently saw a Pentax ME and one of the kit lenses available when new at a favorable price. The lens a 40mm f2.8 pancake lens. My intention was to flip it and make a little profit to fund my addiction to film. The camera doesn't really operate the way I'm use to working with a 35mm, but the camera/lens combination is pretty sweet and would make a great one lens walking around rig. The light seals need replacing, which I can do, however I imagine if I did so, it would be a little harder to let go. I remain Bill and still have way too many cameras. And the beat goes on . . .
